Abstract :
The maximum-likelihood (ML) receiver structure and the corresponding analytical bit-error rate (BER) expressions for a fast-frequency hopped multiple-access (FFH-MA) M-ary frequency-shift-keying (MFSK) system over Rayleigh-fading channels are derived. Numerical results are also presented to illustrate the superiority of the proposed ML receiver in terms of BER. However, the proposed ML receiver requires some side information of the noise and interfering users
