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.
