Investigating High Performance Implementations of Sparse Code Multiple Access (SCMA) Codebook Design

The number of mobile devices, IoT and their applications is increasing day by in recent years further going to increase coming years. These devices demand large connectivity, high throughput, low latency which can be possible only the B5G or 6G. effective utilization spectrum done multiple access techniques facilitate accommodate a users. 5G has different new technologies support massive user high-speed data rate. non-orthogonal scheme (NOMA) considered for NOMA offers connectivity contrast OMA an orthogonal scheme. performance evaluation SCMA investigated advancement field discussed this paper. BER Capacity-based codebook design based on lattice constellation evaluated two channels i.e. AWGN Rayleigh fading channel. behavior capacity-based better than lattice-based design. both designs surpasses channel multipath available Fading
