METHOD FOR COMPENSATING FOR MULTI-PATH OF A CDMA REVERSE LINK UTILIZING AN ORTHOGONAL CHANNEL STRUCTURE

摘要

An apparatus for receiving reverse link signals from a plurality of subscriber units in a multi-path environment is described. The apparatus includes a receiver in a base station that receives a first plurality of reverse link signals and a second plurality of reverse link signals in a time interval. Each reverse link signal of the first plurality of reverse link signals is derived from at least a common pseudo noise (PN) sequence and unique orthogonal sequence and each reverse link signal of the second plurality of reverse link signals is derived from a unique pseudo noise (PN) sequence. The apparatus also includes a a processor that determines a timing offset associated with at least one reverse link signal to align a timing of the at least one reverse link signal with reverse link signals from other subscriber units.
