Convolutionally coded Wideband Code Division Multiple Access in 6G LEO Satellite Communication System

Abstract

The Low Earth Orbit (LEO) network is one of the primary areas of focus for 6G technology. 2020 marked the beginning of 6G research and development, although commercialization may not occur until 2030. LEOs are the ideal choice for 6G due to their lightweight, low cost, and rapid development cycles, which enable them to solve the problem of connectivity in communication-blind places that 5G cannot serve, such as oceans, distant areas, and deserts. This study presents a complete performance evaluation of a convolutionally coded Wideband Code Division Multiple Access (WCDMA) system for the Additive white Gaussian noise (AWGN) channel and the LEO satellite channel. The Bit Error Rate (BER) performance for the proposed system will be formulated and tested using numerical data. Simulation results are demonstrated for a convolutionally coded WCDMA system over an LEO satellite channel for varying numbers of users and coding parameter values. The suggested approach increases the performance of WCDMA-based systems by employing coding gain. Moreover, he results demonstrate that the proposed scheme is superior based on comparing the proposed approach's performance to standard methods without coding.
