Abstract

In the last few years, wireless communication technologies have undergone several advancements. In this context, Unmanned Aerial Vehicles (UAVs) play a vital role. It is a big challenge to get accurate data with minimum collision in UAVs. The features of Direct Sequence Spread Spectrum (DSSS) like multiple access and antijamming are useful to get accurate data with minimum collision. DSSS can transmit and control data. DSSS is a common technique for data transmission. As the number of users increases, DSSS may not be sufficient to transmit and control data. To overcome this problem, we propose a novel hybrid technique for data transmission. The paper introduces a hybrid approach with the combination of Time Division Multiple Access (TDMA) with DSSS. TDMA can divide the frame into equal time slots, so it is easy to access more number of users with minimum data collision. In DSSS, the user data is multiplied with Barker code for spreading and TDMA allocates time slots to each user to allow the same frequency channel by dividing the signal into time slots. The paper uses 13-bit Barker code with the spread spectrum, i.e.,13 users can allow at a time and Bit Error Rate (BER) is evaluated. The work can be carried out in MATLAB.


Introduction

There are many advancements in Unmanned Aerial Vehicles (UAVs). They can be used for navigation, commercial purposes, weather forecast, etc.,(Imad et al., 2017; and Mohammad et al., 2019). They can solve many real-world problems. Due to their broad range of applications and flexibility, they can be used for both Line of Sight (LOS) and long distance communication. In wireless communication, the major problem is interference. In this paper, a novel hybrid technique is used with the combination of both Time Division Multiple Access (TDMA) and Direct Sequence Spread Spectrum (DSSS) to get communication with many users at a time.
