Application of the Difference Threshold Test on BFSK Frequency-Hopped Multiple Access
Jingshown Wu · 1998
Thc ricw side information generating mechanism, difference threshold test (DTT), is proposed to improve the capacity of asynchronous frequency-hopped multiple ac(TSS system with binary frequency shift keying (BFSK) signaling over Rayleigh fading channels. By adjusting the threshold in the DTT decision logic, the optimum capacity (-an bc obtained and proved advantageous over that with conventional hard decision. For thc systems with signal-to-noise ratio ranging from 10 to 13 dB, this improvement ('ail over 12%.
