The performance of coded FHMFSK with list metric detection is presented for two severe jamming channels, the single-tone and multiple-tone jamming channels. It is shown that list detection is a highly efficient soft decision quantization scheme for tone jamming provided that channel state information in the form of list position probabilities is available. Results indicate an improvements in EbNo performance of greater than 10 dB over hard decision performance when large alphabets and large list sizes are used. Optical jamming fractions are derived, and in all cases the optimal jamming is less than full-band. Author
