Expanded LS Code in MC-DC-CDMA system
This paper presents a novel multicarrier DS-CDMA scheme based on the loosely synchronous (LS) codes, which can achieve very high spectral efficiency and better performance. We present a method to extend LS code on complex plan, with detail description of its construction, and give proof of some properties on such code. At last, simulation results show that the example code has better performance than 8PSK and 8QAM. In practice,this method can be expanded to construct longer LS code, and further improve system performance.
