Abstract : A robust scheme, called list-metric detection, is presented for coded MSFK/FH signaling. In this technique, demodulator outputs are ranked in magnitude and decoder metrics are assigned according to their position in the ranking. The cutoff rate parameter Ro which characterizes the coding channel is derived for fixed metric assignments and optimum adaptive metrics. Results are given for the optimum metric case for both the Rayleight fading channel and a worst-case tone jamming channel. These results show that list-metric detection provides performance superior to hard-decision for all cases considered. (Author)
