A receiver has been provided, with a pre-whitening filter, to improve the probability of recovering a received signal in the presence of colored noise. Colored noise can be multipath or transmission signals to other receivers in the same spectral bandpass. The receiver system uses colored noise statistics to provide an optimal estimation in the despreading of the transmitted information. Auxiliary systems in the receiver cancel the pilot, or system acquisition symbols, improving even further the probability or recovering information in the despreading of transmitted signal. A method of pre-whitening a signal received in the presence of colored noise is also provided.

1. In a multiple access communication system including at least one base station transmitting to mobile station in a bandwidth that is large compared to the information transmission rate, a method for removing colored noise from received communications wherein the communications are received across a spectrum of frequency bandwidth, comprising the steps of:a) receiving communications including information, colored noise, and white noise; and b) selectively weighting portions of the frequency spectrum when the received communications are despread to emphasize the signal to noise ratio.
