Abstract

The performance analysis of a fast frequency-hopped binary frequency-shift-keying (FFH/BFSK) spread-spectrum (SS) system in conjunction with a fast Fourier transform (FFT) processor is presented. Under the conditions of partial-band jamming (PBJ) and additive white Gaussian noise (AWGN), the bit-error rate (BER) expressions of the proposed FFT-based product-combining receiver (PCR) are derived in terms of the characteristic functions of the decision statistics. The BER expressions, validated by simulation results, are applicable to any arbitrary diversity level. The BER results show that there is an optimum diversity level for the FFT-based PCR. The FFT-based PCR is also shown to perform better than the well known square-law linear-combining receiver
