Abstract :
A dynamic digital matched filter (DDMF) with recurring state is proposed for DS-CDMA. The proposed DDMF is analysed, implemented and its performance is tested and compared to the conventional DMF in the presence of AWGN and interference. The probabilities for detection and false alarm in the AWGN channel are derived and the mean acquisition time is evaluated as a measure of performance.
