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.

The main goals of all new technologies nowadays are utilizing the available spectrum, increasing spectrum efficiency, and increasing the throughput. Cognitive radio (CR) technology can provide efficient spectrum utilization and maximize the throughput using dynamic spectrum access technique. A new medium access control (MAC) protocol is needed for CR users to access the spectrum dynamically and to maintain fairness between users. In this paper, our objective is to enhance the overall network throughput, by enhancing SMART-V MAC protocol to support D-OFDM technology. A new channel assignment scheme called SMART-O based on these two technologies is proposed. The proposed algorithm greatly increased the overall throughput of the network and solved the channel assignment and rate optimization problems. Simulation results exposed the improvement of our work compared to previous algorithms.
