A method and apparatus for adaptively despreading a direct sequence spread spectrum signal. The direct sequence spread spectrum signal is provided to a transversal filter. The output of the filter is demodulated to provide a soft symbol. The soft symbol is provided to an error corrector which generates an error corrected version of the soft symbol, referred to as a hard symbol. The value of the hard symbol is subtracted from the soft symbol to generate an error symbol. The error symbol is then used to compute tap values of the transversal filter by an LMS algorithm.
