Energy-Efficient Cooperative Relay Wireless Communication Networks: A Review

--Preeti Jwala Ekka, Anurag Shrivastava and Anjulata Yadav

Energy consumption issues are the fastest growing research area in wireless communication network. Cooperative relay communication technique is a solution for minimizing the energy of overall wireless communication network. A number of techniques have been proposed to minimize the energy consumption of the network. This paper gives an overview of the different cooperative relay communication networks.

Network Synchronization Techniques for Dense Small Cell Cellular Networks

--Neha Septa, Preeti Trivedi and Shekhar Sharma

The paper provides an overview of improvement of the coverage and capacity of cellular network using many techniques, such as power control, MIMO, intra and inter base station and SDMA, and also of network synchronization techniques. Long-Term Evolution (LTE) release 10 and LTE 12 focus more on small cell enhancement. Heterogeneous networks are very important topic of 3GPP LTE-advanced. Clock synchronization IEEE 1588 is a practical solution to improve the problem-related synchronization. Most important LTE 230 is designed for the smart grid which is used to transfer the information through wireless media using synchronization signal. The details of existing network synchronous techniques, an improved design and algorithm and their limitation in small cell networks are described.

Optimization of FSO System Parameters Under Varying Meteorological Conditions in Delhi

--Disha Srivastava and Gurjit Kaur

Free Space Optical (FSO) communication offers a promising technology for future high speed networks by providing huge transmission bandwidth, light weight, small size, low cost, low power and license free deployment as compared to the present radio frequency systems. Since in FSO communication, the atmosphere is used as a channel, atmospheric turbulence effects cause fading and misalignment of signal at the receiver and deteriorate the Bit Error Rate (BER) performance. This paper is focused on analyzing the FSO communication system performance in Delhi by modeling FSO communication system using basic Wavelength Division Multiplexing (WDM) technique with optimizing several system parameters in different turbulent environments such as fog and rain. Performance is analyzed in terms of Signal-to-Noise Ratio (SNR), received optical power and BER for different meteorological effects at data rate of 2.5 Gbps, 5 Gbps and 15 Gbps. From the results, it is concluded that the quality of received signal can be improved with priority-based optimization of parameters that increases link range up to 115 km in clear weather condition at 15 Gbps.

Robust Beamforming Algorithms for Smart Antenna Systems

--Veerendra, Md. Bakhar and Vani R M

In this paper, the performances of well-known adaptive beamforming algorithms, namely, Sample Matrix Inversion (SMI) and Least Mean Square (LMS), are analyzed. From the simulation results, it is observed that for SMI, as the number of user increases the main lobe spreads in all directions. As a result, beamforming in the user direction may not be correct. To overcome this, LMS algorithm can be used. The LMS algorithm is the best choice in most of the commercial wireless applications due to its low complexity. 5G and beyond 5G networks require beamforming algorithms with high directivity and fast convergence rate. Hence, in this paper, LMS algorithm is modified to improve the convergence rate. Furthermore, improved LMS algorithms are applied to horizontal – vertical Uniform Linear Array. This is also called 2D-ULA. These improved LMS algorithms are called 2D-LMS 1 and 2D-LMS 2. The main drawback of LMS algorithm is its low convergence rate; because of this, LMS algorithm may not track the desired signal when the signal conditions are changing rapidly. Simulation results show that the proposed 2D-LMS 1 and 2D-LMS 2 algorithms have improved convergence rate, higher directivity, low complexity and fast execution time as compared to conventional LMS algorithm. Hence, the proposed algorithms are best suited for 5G and beyond wireless communications.

Profiling Techniques in QuestaSim and Design of a Profiler Hardware Module

--Ashish Mishra, Suhas B and Suresh Kumar

Estimation of execution time for any module in software or in hardware guides the designer of its efficiency. The paper presents the profiling techniques present in QuestaSim hardware simulator for Field-Programmable Gate Array (FPGA) and System on Chips (SOCs). Different statistical and memory profiling techniques present in QuestaSim have been explained. An 8-bit Reduced Instruction Set Computing (RISC) processor has been designed for identifying the usefulness of the simulator. Various profiling reports have been generated and analyzed for the designed processor. The processor has been further extended by writing a module which counts the number of cycles taken by a unit. This module returns the count the number of times a function has been called. This module also gives the information such as how many different functions have been called, total number of different instructions, how many times each and function has been called.

Automated Teller Machines (ATMs): The Changing Face of Banking in India

Bank Management
Information and communication technology has changed the way in which banks provide services to its customers. These days the customers are able to perform their routine banking transactions without even entering the bank premises. ATM is one such development in recent years, which provides remote banking services all over the world, including India. This paper analyzes the development of this self-service banking in India based on the secondary data.

The Information and Communication Technology (ICT) is playing a very important role in the progress and advancement in almost all walks of life. The deregulated environment has provided an opportunity to restructure the means and methods of delivery of services in many areas, including the banking sector. The ICT has been a focused issue in the past two decades in Indian banking. In fact, ICTs are enabling the banks to change the way in which they are functioning. Improved customer service has become very important for the very survival and growth of banking sector in the reforms era. The technological advancements, deregulations, and intense competition due to the entry of private sector and foreign banks have altered the face of banking from one of mere intermediation to one of provider of quick, efficient and customer-friendly services. With the introduction and adoption of ICT in the banking sector, the customers are fast moving away from the traditional branch banking system to the convenient and comfort of virtual banking. The most important virtual banking services are phone banking, mobile banking, Internet banking and ATM banking. These electronic channels have enhanced the delivery of banking services accurately and efficiently to the customers. The ATMs are an important part of a bank’s alternative channel to reach the customers, to showcase products and services and to create brand awareness. This is reflected in the increase in the number of ATMs all over the world. ATM is one of the most widely used remote banking services all over the world, including India. This paper analyzes the growth of ATMs of different bank groups in India.
International Scenario

If ATMs are largely available over geographically dispersed areas, the benefit from using an ATM will increase as customers will be able to access their bank accounts from any geographic location. This would imply that the value of an ATM network increases with the number of available ATM locations, and the value of a bank network to a customer will be determined in part by the final network size of the banking system. The statistical information on the growth of branches and ATM network in select countries.

Indian Scenario

The financial services industry in India has witnessed a phenomenal growth, diversification and specialization since the initiation of financial sector reforms in 1991. Greater customer orientation is the only way to retain customer loyalty and withstand competition in the liberalized world. In a market-driven strategy of development, customer preference is of paramount importance in any economy. Gone are the days when customers used to come to the doorsteps of banks. Now the banks are required to chase the customers; only those banks which are customercentric and extremely focused on the needs of their clients can succeed in their business today.
