Performance analysis of a noise-normalized FFH/MFSK receiver over Rayleigh fading channels with partial-band noise jamming
Fast frequency hopping can reduce the degradation caused by interference. The performance of noise-normalized fast frequency-hopped M-ary orthogonal frequency-shift-keying (FFH/MFSK) receivers over frequency nonselective Rayleigh fading channels with partial-band noise jamming is analyzed. Instead of numerical evaluation, a closed-form error probability expression is given based on the theory of complex variables. The simulation results validate the analytical results. It is shown that there is an optimum diversity order and the system performance gets better with an increase in the modulation order.
