Abstract
A new side information generating mechanism, the difference threshold test (DTT), is proposed to improve the capacity of asynchronous frequency-hopped multiple access systems with binary frequency shift keying (BFSK) signalling over Rician fading channels. By adjusting the threshold in the DTT decision logic, optimum capacity can be obtained. This technique has proven to be advantageous compared with the conventional hard decision technique. For systems with signal-to-noise ratio ranging from 10 to 13 dB, this improvement can be >13%.
