Multi-User Detection Based on Quasi-Synchronous CDMA Systems

Abstract:

Multi-user detection is one of the key technologies of CDMA systems. Its basic idea is that, all user signals are considered as useful signals. Then, we can use them to eliminate multiple access interference (MAI). This paper presents an improvement of multi-user detection based on QS-CDMA systems. By the improving, computational complexity is lower, and performances approach synchronous CDMA systems.
