Abstract

The Bit Error Rate (BER) performance of optical phase diversity FSK receivers of both single filtered (LPF1 in Fig. 1) and dualfiltered version (LPF1 and LPF2 in Fig. 1) is analyzed. The effects of several key system parameters (e. g. the bandwidth of LPF1 the amount of laser phase noise the frequency deviation employed the delay time r in the frequency discriminator etc. ) on receiver performance are investigated in detail. Clear system design guide rules have also been obtained. The analysis has been focused on obtaining expressions for the probability distribution functions (pdf''s) of the signal v at the sampler output. The derivation does not use Gaussian approximations and is therefore more accurate. The results are valid for any value of delay time r.
