Techniques on Controlling Bandwidth and Energy Consumption for 5G and 6G Wireless Communication Systems

Abstract

This work aims at exploring novel modulation schemes and waveform designs for 5G and the emerging 6G telecommunication systems for high band width utilization and energy consumption. Thus, as generation of wireless communication networks progresses, requirement toward higher data rate, lower delay and power consumption increases, encouraging the emergence of new layer of modulation. This paper reviews more advanced waveforms for 5G systems, such as f-OFDM, GFDM, and NOMA which enable higher spectral efficiency and better interference tolerance. Further, we unravel various modulation schemes including AMC and higher order QAM through which modulation and coding rate can be selected based on the quality of channel to allow maximum throughput with minimal power consumption. The efficacy of these new schemes in scenarios of the proposed system is tested through simulations and analysing analytical models by comparing parameter such as bandwidth usage, error rates and energy efficiency of these new schemes to conventional modulation techniques like OFDM. The analysis demonstrates that these novel solutions can enhance the total efficiency of the following generation communi- cation networks by enhancing the potential of the crucial use instances of 5G and 6G realizations, such as M มC, URLLC, and eMBB. Hence, this research is part of the continuing endeavours to advance better techniques for wireless communication.
