Abstract:The Bit Error Rate (BER) performance of a noncoherent Fast Frequency-Hopped Binary orthogonal Frequency-Shift-Keying (FFH/BFSK) Spread Spectrum (SS) receiver with Adaptive Gain Control (AGC) is investigated in the presence of Partial-Band Jamming (PBJ) and Additive White Gaussian Noise (AWGN) over frequency non-selective slow Nakagami-fading channels. Exact BER expressions in a one fold integral is derived. The effects of arbitrarily values of fading parameter and diversity level on system performance are considered. Numerical results compare the worst case BER performance of the AGC receiver with that of the Product Combining (PC) receiver. Compared with the former BER analysis method,the advantage of this paper lies in the uniform analysis mode so that the analysis of the performance of the system under different fading channels is simply a analysis step。
