Consider shadow rain attenuation and multipath effects Chaos-based simulated annealing algorithm, LZ complexity is reflected in a time sequence.

LZ complexity is reflected in a time sequence, Transceiver contains two client programs, Use of natural gradient algorithm.

Being an effective non-orthogonal multiple access (NOMA) technique, sparse code multiple access (SCMA) is promising for future wireless communication. Compared with orthogonal techniques, SCMA enjoys higher overloading tolerance and lower complexity
