摘要：
A multistage multiuser detection (MUD) technique, the Adaptive Duplicated Filters plus Interference Canceller (ADIC), is proposed in the DS-CDMA context. Of particular interest is the use of adaptive filters block (AFB) dedicated to each user with its respective input signals independent from other users' contributions. These AFB are mixed with interference canceller block in a cascade arrangement. As shown in this paper, this proposed MUD can outperform the Decision Feedback Soft Multi Stage Interference Canceller (DF-Soft-MPIC) MUD with complexity reduction of 4. Algorithmic description and performance of low complexity MUD method are considered in this paper and FPGA implementation in a companion paper, Part II.
