摘要
This letter considers the implementation of Non-Orthogonal Multiple Access (NOMA) scheme with different waveforms. The performance of the adopted Multi-Carrier Modulations (MCM)-based NOMA system is evaluated in doubly selective channel scenario. In addition, the imperfect Successive Interference Cancellation (SIC) process is analyzed, wherein a joint iterative algorithm is introduced. The proposed algorithm cancels both weaker users interference signal and the non diagonality of the MCM System Transmission Matrix (STM) resulted from imperfect Successive Interference Cancellation (SIC) and the doubly selectivity, respectively. Furthermore, numerical simulations are performed to prove the efficiency of the introduced joint technique when compared to the theoretical perfect SIC case.
