摘要：
We show that non-orthogonal multiple access (NOMA) and orthogonal multiple access (OMA) have similar performance in systems with centralized control and perfect channel state information (CSI). Otherwise, NOMA has distinct advantages over OMA. We outline a randomized power control (RPC) strategy for NOMA. RPC can provide significantly enhanced throughput in random access systems with successive interference cancelation (SIC) or iterative detection. We also show that interleave division multiple access (IDMA) is a simple implementation technique for NOMA to facilitate RPC.
