SCMA, (Code Multiple Access Sparse) Sparse code multiple access is a kind of non orthogonal multiple access technology, which should be produced by the design of 5G demand. Encoding bit mapped into SCMA code word by multi dimensional modulation and sparse spread spectrum at the transmitter, and the receiver can decode the data by multi user detection. Compared to the OFDMA 4G technology, it can be achieved in the same amount of resources under the conditions, while serving more users, so as to effectively enhance the overall capacity of the system.
