Abstract :
In this paper, we study the bit error probability (BEP) performance of one-bit delay differential detection of narrow-band frequency shift keying (FSK) signals transmitted over flat Hoyt fading channels and corrupted by additive white Gaussian noise (AWGN). Both the Doppler effects and the inter-symbol interference (ISI) introduced by the pre-detection filter are considered in the evaluation of the BEP performance. By assuming a Hoyt mobile-to-mobile (M2M) fading channel, numerical examples for the BEP of differential detection are depicted. Furthermore, the obtained results are compared with that of limiter-discriminator-integrator (LDI) detection, for different values of the FM system parameters and the fading characteristics.
