Block Decision Feedback based Joint Detection Algorithm for TD-SCDMA and Its VLSI Implementation
TD-SCDMA中基于块判决反馈的联合检测算法及其VLSI实现

A new Joint Detection (JD) algorithm, named as Block-Decision-Feedback based Joint Detection (BDF-JD), is proposed for TD-SCDMA. Comparing to the existing algorithms, BDF-JD has much less computational complexity and comparable performance, and is very suitable for terminals. Based on BDF-JD, the architecture of the JD coprocessor is proposed. Implemented with the 0.18 μ m process of SMIC, the coprocessor only consumes 160 k gates.
