Abstract
A rigorous theoretical model for CPFSK receivers with post-detection filtering is presented. The sensitivity is within 0.3 dB of the best result (i.e. 36 received photons for a 10-9 error probability) for modulation index between 1.5 and 5. The sensitivity is better than the matched filter sensitivity in some cases. The phase noise tolerance is significantly improved.
