Abstract
The performance of codes for the coding channel under a worst case multitone jamming, using FH/MFSK signalling with multichannel diversity, is investigated. On the assumption that the receiver combiner is supplied with jammer state information, it is found that the rate 1/3 convolutional code with no diversity and soft decision decoding exhibits the best performance in terms of the bit energy-to-noise power spectral density ratio. Results obtained in this investigation reveals that codes over larger alphabets, such as rate 1/2 dual-k codes and Reed-Solomon codes with errors only decoding do not perform very well under a worse case jamming environment.
