Abstract

The new side information generating mechanism, difference threshold test (DTT), is proposed to improve the capacity of asynchronous frequency-hopped multiple access system with binary frequency shift keying (BFSK) signaling over Rayleigh fading channels. By adjusting the threshold in the DTT decision logic, the optimum capacity can be obtained and proved advantageous over that with conventional hard decision. For the systems with signal-to-noise ratio ranging from 10 to 13 dB, this improvement can be over 12%
