A decision-aided implementation of a GLR-based detector designed to demodulate the bits of G out of the K users of a synchronous DS/CDMA system is proposed. The GLR-based detector does not require knowledge of the bits, the amplitudes, and the signatures of the interferers; in addition, its decision-aided implementation resorts to the training sequence, necessary to initialise the algorithm, to estimate the channel impulse response and to the AIC to determine the number of interferers.
