Implementation of Successive Interference Cancellation Scheme in IS-95 DS/CDMA system

摘要

Compensating for near/far effects is critical for satisfactory performance of DS/CDMA systems. So practical systems have used power control to combat the near/far effect. Another approach, which has a fundamental potential in not only eliminating near/far effects but also in substanctially raising the capacity, is multiuser detection and interference cancellation. There are serious complexity and implementation issues associated with optimal scheme and also with many suboptimal schemes. Here we discuss a simple interference cancellation(SIC) prototype working with a power control with relaxed requirements in IS-95 system.
