摘要

在窄带干扰(NBI)存在的情况下，采用多种干扰消除方案可以提高直接顺序码分多址(DS-CDMA)通信系统的性能。为了提高信干扰比和处理多址干扰效应，提出了一种并行干扰消除器方案，该方案包括一组近端对消滤波器和一组多址干扰消除滤波器。为了避免由于不可靠的初始检测而导致性能下降，在我们提出的设计准则中引入了鲁棒系数/spl γ /。

Adaptive narrow-band interference cancellation in DS-CDMA communications

In the presence of narrowband interference (NBI), the performance of direct-sequence code-division multiple access (DS-CDMA) communication systems can be improved by using various interference cancellation schemes. A scheme of parallel interference cancellators (PIC), which includes a set of NBI cancellation filters and a set of multiple access interference (MAI) cancellation filters, is developed to improve the signal-to-interference ratio (SIR) and handle the MAI effect. In order to avoid performance deterioration due to the unreliable initial detection, a robust coefficient /spl gamma/ is introduced in our proposed design criterion.
