Combination of Asymmetric PCMA and Common Multiple Access Technology

摘要

Aiming at the transmission efficiency of asymmetric PCMA communication and the improvement of its communication capacity, the full use of the characteristics that PCMA technology can be combined with common multiple access technology can be realized by transmitting multiple small signals in a large signal band. Firstly, the method of asymmetric PCMA combined with FDMA and CDMA is introduced in principle. Then, the influence of parameter estimation error on the demodulation performance of asymmetric PCMA under different multiple access technologies is analyzed by simulation. Finally, for two kinds of multiple access technologies, Corresponding analysis and conclusions are given after comparison.
