Abstract :
The interleaving span of coded frequency-hopped systems is often constrained to be smaller than the decoder memory length, i.e. nonideal interleaving is performed. Analysis of the performance of a hard-decision decoder and an erasure-control decoder of Reed-Solomon codes is presented, both for ideal and nonideal interleaving. The interference consists of worst-case partial-band noise jamming and thermal noise. The frequency hopping system considered uses orthogonal MFSK modulation and noncoherent demodulation with quality bit output based on Viterbi´s ratio-threshold technique. Optimization of the ratio-threshold and the erasure-control parameters is performed in worst-case partial-band jamming, and the resulting performance for several interleaver spans is presented.<>
