    摘要: A CDMA receiver with parallel interference suppression and with weighting. The weighting coefficients of the outputs from the various stages of the receiver are chosen in order to minimize a quadratic error weighted by the distribution of the pertinent values of the intercorrelation matrix.

    摘要: A method for processing a direct sequence spread spectrum signal, and a receiver for performing the method. A correlation is preformed between a received signal and the direct sequence used to determine peaks of different amplitudes. The spectrum of the information corresponding to the highest amplitude peak is respread using the direct sequence. The respread signal is subtracted from the received signal to create a new signal. This process is reiterated on the new signal until all of the peaks have been exhausted.
