Erasure Insertion in RS-Coded SFH MFSK Subjected to Tone Jamming and Rayleigh Fading

In this paper, the achievable performance of Reed–Solomon (RS)-coded slow-frequency-hopping assisted $M$ -ary frequency-shift keying using various erasure-insertion (EI) schemes is investigated when communicating over uncorrelated Rayleigh fading channels in the presence of multitone jamming. Three different EI schemes are considered, which are based on the output threshold test, on the ratio threshold test, and on the joint maximum output–ratio threshold test. The relevant statistics of these EI schemes are investigated mathematically, and based on these statistics, their performance is evaluated in the context of RS error-and-erasure decoding (EED). It is demonstrated that the system performance can be significantly improved by using EED, invoking the EI schemes considered.
