Abstract:

A frequency-hopping binary frequency shift keying BFSK ratio- statistic receiver with multi-hops per data bit is an effective electronic countermeasures ECCM system against partial-band jamming interference. Interference is modeled as Gaussian noise. Orthogonal binary signaling and independent fading diversity is considered over frequency-nonselective, slow fading Rayliegh, Rician, and Gaussian channels. Forward error correcting coding scheme is implemented for a 12 convolutional code. The probability of bit error is examined for different levels of diversity, thermal noise, severity of fading, fractions of bandwidth jammed, and jamming power. Uncoded and coded system comparisons are done to determine worst case performance.
