摘要
In a direct sequence spread spectrum receiver, spread orthogonal data signals and spread orthogonal pilot signals are correlated with orthogonal despreading sequences at a chip rate. These despread signals are integrated at a symbol rate to produce orthogonal data symbols and orthogonal pilot symbols. A predetermined number of pilot symbols of each phase component is moving-averaged. Each phase component of the orthogonal data symbols is weighted with the moving average value of the corresponding phase component of the pilot symbols, and summed with the other weighted component of the data symbols to produce an output signal of the spread spectrum receiver.
