A parallel equalizer for a DS-CDMA UWB system and method thereof are provided. The parallel equalizer includes: a filter block for filtering a training input signal in a ‘training mode’, and filtering the plurality of input signals in parallel in a ‘symbol decision mode’; a symbol decision block for obtaining a symbol error based on a output from the filter block and a training symbol in the ‘training mode’, and estimating a transmission symbol for each of the input signals in the ‘symbol decision mode’, obtaining an error of one among the estimated transmission symbols for a symbol error calculating input signal; and an weight update block for updating a filter tap coefficients of the filter block based on the training input signal or the symbol error calculating input signal and the symbol error and transmitting the updated filter tap coefficients into the filter block.
