    • A receiver which suppresses inter-cluster multipath interference by processing an impulse channel response consisting of two multipath clusters, each cluster having groups of signals with multiple delays. In one embodiment, the receiver includes a single antenna and parallel-connected delay units used to align the groups of signals before being input into respective sliding window equalizers. The outputs of the equalizers are combined at chip level via a combiner which provides a single output. In another embodiment, a Cluster Multipath Interference Suppression (CMIS) circuit is incorporated into the receiver. The CMIS circuit includes a hard decision unit and a plurality of signal regeneration units to generate replicas of the multipath clusters. The replicas are subtracted from the respective outputs of the delay units and the results are input to the respective sliding window equalizers. In another embodiment, multiple antennas are used to receive and process the clusters.
    • 一种通过处理由两个多径簇组成的脉冲信道响应来抑制簇间多径干扰的接收机,每个簇具有多个延迟的信号组。 在一个实施例中,接收机包括单个天线和并联连接的延迟单元,用于在输入到相应的滑动窗口均衡器之前将信号组对准。 均衡器的输出通过提供单个输出的组合器在芯片级组合。 在另一个实施例中,集群多路径干扰抑制(CMIS)电路并入接收机。 CMIS电路包括硬决策单元和多个信号再生单元以生成多路径簇的副本。 从延迟单元的相应输出中减去副本,并将结果输入到各个滑动窗均衡器。 在另一个实施例中,使用多个天线来接收和处理簇。
