Telecommunications is an exciting branch of engineering. It unravels the marvels of modern communication technology that is growing rapidly using the advancements in Microelectronics and Computers. Telecommunication has been acknowledged as a vital ingredient of economic growth. It is to realize this growing importance of the field that IUP has come up with a quarterly journal, The IUP Journal of Telecommunications. We are sure that the academic fraternity will encourage us—as they have done in all our previous endeavors—by availing this facility for publishing their research works.

Delay-Sensitive Smart Polling in Dense IEEE 802.11n Network for Quality of Service

--H Vishalakshi Prabhu and G S Nagaraja

In this paper, the polling mechanism of IEEE 802.11n standard is examined with the objective of reducing the delay induced by polling a large number of stations in crowded hotspot. This standard, also known as high speed Wireless Local Area Network (WLAN), is competent to become carrier Wi-Fi in the Evolved Packet Core (EPC). Scheduling algorithms are playing a major role in yielding QoS in high speed wireless networks of next generation. IEEE 802.11n standard has some support for Quality of Service (QoS)-based scheduling, but one that focuses on polling is not dealt with much in detail. Polling is a centralized scheduling which is initiated by the Access Point (AP) to poll user stations. Most of the proposed polling mechanisms introduce delay when the number of stations under a given access point increases. The aim of this paper is to introduce new polling algorithm based on two-level priority queues to reduce the polling delay in a crowded WLAN hotspot. This in turn assures the QoS guarantees for delay-sensitive applications. The new algorithm is named as Smart_Poll. The paper also discusses the performance estimation of the proposed smart polling by comparing it with traditional polling.

Massive MIMO Challenges and Emerging Research Directions: A Review

--Ankita Sahu, Manish Panchal and Rekha Jain

Advancement in information and communication systems leads to next generation wireless networks that should support higher capacity and data rate, low end-to-end latency, low infrastructure cost and high energy efficiency. To support next generation requirements, 5G will be the most prominent network based on massive MIMO (mMIMO). mMIMO has multiple number of antennas that help to fulfill the requirements of 5G, but there are some issues like pilot contamination, hardware impairments, inter-antenna correlation due to space constraints and non-orthogonal waveform design that needs to be rectified for utilizing advantages of mMIMO sufficiently. The paper reviews the various limitations and relevant techniques to solve these shortcomings of 5G wireless network.

Design and Implementation of Crosstalk Avoidance Using Bit-Stuffing Algorithms in VLSI Circuits

--B Jyothi and B Obulesu

Crosstalk is one of the major problems in VLSI circuits of high-speed buses. To eliminate this problem, several types of coding techniques have been proposed in the literature. The paper aims at avoiding the opposite transition on any two adjacent wires. Sequential bit-stuffing algorithm and parallel bit-stuffing algorithm are studied. The problem in parallel bit-stuffing algorithm is that the code rates for even-numbered wires are significantly lower than those of odd-numbered wires. To solve the uneven rate problem, the paper considers parallel bit-stuffing algorithm with rate balancing, where padding of additional bits on odd-numbered wire with the help of 2 ´ 2 crossbar switch with bar state and cross state is done. By doing so, even-numbered code rate becomes equal to odd-numbered code rate, then code rates become balanced. Parallel bit-stuffing algorithm with rate balancing not only achieves higher coding rate but also lowers power consumption.

Implementation of Crosstalk Avoidance and Low Power Coding Scheme for SoC

--D Chakradhar and B Obulesu

The paper proposes a coding scheme for avoiding crosstalk and reducing power consumption. System-on-Chip (SoC) buses are associated with delay, power and reliability problems. Capacitive crosstalk and high power consumption due to various capacitances are the major causes of this problem. Verilog simulation of encoder and decoder modules are designed to avoid these problems.

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.
