Abstract
The possibility of applying non-orthogonal multiple access technology with compound modulation scheme for future 5G networks to improve the overall spectral and spatial efficiency is investigated. Calculation method of channel capacity for Power Division Non-orthogonal Multiple Access (PD-NOMA) with combined spatial modulation (SM) and amplitude phase modulation schemes is developed. Throughputs of PD-NOMA and Frequency Division Multiple Access (FDMA) techniques are compared. Numerical calculations and simulation show that in some scenarios the total capacity in the case of using PD-NOMA is about 1.6 times higher as for FDMA multiplexing technique.
