Abstract :
Analytical expressions of bit-error rate (BER) are derived for a fast-frequency-hopping M-ary frequency-shift- keying (FFH/MFSK) spread-spectrum communication system over frequency-selective Rayleigh-fading channels with multitone jamming (MTJ) and additive white Gaussian noise. The FFH/MFSK systems employing a linear-combining receiver (LCR) and a product-combining receiver (PCR) are studied. The desired signal and MTJ are assumed to undergo independent fading. The characteristic function approach is used to derive the analytical BER expressions for higher diversity levels. The analytical BER expressions are validated by simulation results and the PCR is found to outperform the LCR when the jamming power is relatively strong.
