Analysis of Approximate Decorrelation Decision-Feedback Receiver for Dual-Rate Asynchronous DS/CDMA System
Chengshu Li · 2001
The research on multiuser receiver for dual-rate system is mainly decorrelator-based for synchronous CDMA system. This paper puts forward an approximate decorrelation decision-feedback receiver for asynchronous dual-rate DS/CDMA System. For high rate users, it's effect is equal to approximate decorrelation. But low rate users improve performance by use of the decision-feedback of the high rate users. Calculation and simulation results are compared to both high rete users and low rate users.
