A crosscorrelation reduction receiver robust to the near-end effect

A receiver was developed to operate in the near-far interference situation commonly occurring in direct-sequence/spread-spectrum multiple-access communication systems. The receiver was designed to provide robustness to the interference of one unintended user blocking the intended signal at the receiver under consideration. The improvement over a standard correlation receiver was accomplished by using the three-valued property of the crosscorrelation of Gold spreading sequences to identify and subtract the interference from the intended signal. The performance of this receiver is analyzed using Monte Carlo analysis and the results are compared to the standard correlation receiver.<<ETX>>
