Abstract

A receiver for a signal that includes several symbols modulated with a pseudonoise sequence and that travels to the receiver along a plurality of paths in a channel. The receiver includes a matched filter (34) for correlating the signal with the pseudonoise sequence to produce a correlation function. The receiver also includes a delay estimator (36) for estimating a delay for each of the paths from the correlation function and a number of correlators (40) for correlating the signal with the pseudonoise sequence in accordance with the delays.
