| Abstract | ||
| This paper focuses on the performance comparison of two direct sequence spread spectrum (DSSS)systems one system using Gold code and the other system using Walsh code under the effect of single tone jamming(STJ) and multi tone jamming(MTJ) in presence of Additive White Gaussian Noise (AWGN) channel ,thesetwo systems was carried out by using MATLAB program. The performance evaluation of two systems was tested by measuring the bit error rate (BER) of receiving data for different cases of energy per bit to noise power spectral density ratio (Eb/No) and also for different cases of jamming to signal power ratio (J/S). The comparison results showed the BER of DSSS system using Gold code is better than the system that using Walsh code under the effect of both STJ and MTJ in communication channel. | ||
