Probability of error for a hybrid DS/SFH spread-spectrum system under tone jamming

A hybrid direct-sequence slow-frequency-hopped (DS/SFH) spread-spectrum system is used to achieve a larger gain in some applications. The probability of error for a hybrid DS/SFH spread-spectrum system is calculated over a channel which suffers from multiple-tone jamming and additive white Gaussian noise (AWGN). Binary phase-shift keying (BPSK) is used for data modulation. The probability of error is computed for various system parameters, such as DS/SFH hybrid ratio, the number of jamming tones, a jamming-to-signal ratio, and a signal-to-noise ratio. It is shown that there are hybrid ratios with which a hybrid DS/SFH system achieves smaller probability of error than a DS system and a SFH system achieve for some values of system parameters.<
