摘要

将离散小波多元(DWMT)技术与码分多址(CDMA)技术相结合，在NBI信道上传输数据会产生窄带干扰(NBI)和多址干扰(MAI)。在本文中，我们解决了干扰抑制和处理增益保护的多用户检测与较少的噪声增强使用并行抵消方案。为了避免并行对消方案中由于初始估计不可靠而导致的性能下降，引入了一个具有适当设计准则权重的代价函数来提高所提检测器的性能。

Adaptive narrow-band interference rejection in DWMT-CDMA communications

While combining discrete wavelet multiton (DWMT) with code division multiple access (CDMA) systems, both narrow-band interference (NBI) and multiple-access interference (MAI) arise when data is transmitted over NBI channels. In this paper, we address interference suppression and processing gain protection for multiuser detection with less noise enhancement by using a parallel canceling scheme. In order to avoid performance deterioration due to unreliable initial estimation in the parallel cancellation scheme, a cost function with proper weighting of design criterion is introduced to improve the performance of the proposed detector.
