一种基于主从均衡器结构的chip级接收机

A Chip Level Receiver Based on the Construction of MS Equalization

在高速数据传输环境下,多径传播使码分多址(Code division multiple access,CDMA)系统中的多址干扰(Multiple access interference,MAI)和码间干扰(Inter-chip interference,ICI)变得非常严重。针对此问题,文章提出一种新的接收机结构,并在实际系统中验证该接收机与线性最小均方差均衡器(LMMSE-chip均衡器)和Rake接收机相比在性能、鲁棒性以及实现复杂度上的优势。

In the high-speed data transmission, multiple access interference（MAI） and inter-chip interference（ICI） in the code division multiple access（CDMA） systems become serious because of the multi-path propagation. A low complexity chip receiver for CDMA systems is proposed. In addition to considerably reduced complexity, the proposed receiver has shown significant performance improvement and robustness gains com- pared to the LMMSE-based chip-level equalizer and the Rake receiver.
