Abstract :
A bit error rate (BER) analysis of binary DPSK data modulation used in conjunction with direct sequence spread sprectrum (DSSS) is presented. A first order noncoherent delay-lock loop is used for the pseudonoise code tracking. Conditional BER results for the DS/DPSK systems for fixed values of the code tracking error are obtained. The average BER of the system is then evaluated by averaging the conditional BER expressions over the probability density function of the code tracking error. These results are supplemented by considering the effects of a narrowband fading tone interferer on the overall system performance.
