Signature Design of Sparsely Spread Code Division Multiple Access Based on Superposed Constellation Distance Analysis
Sparsely spread code division multiple access (SCDMA) is a non-orthogonal superposition coding scheme that allows concurrent communications between a base station and multiple users over a common channel. However, the detection performance of an SCDMA system is mainly determined by its signature mat...
