Performance comparison of DS signal data detection using matched filter with median filter and with transversal filter

This paper introduces analysis and simulation results of a DS spread spectrum system in which data detection is based on a matched filter and a median filter and a matched filter and a transversal filter, The probability of bit error is calculated in the AWGN channel and with continuous tone jamming with ideal autocorrelation of the spreading code being assumed. The effect of CW jamming can be eliminated by both methods, so the comparisons are made in the AWGN channel. It is concluded that the median filter causes a loss compared to the transversal filter. The loss is about 1.2 dB when the window length is the minimum. The loss decreases as the window length increases, being about 0.35 dB with window length 7
