Abstract :
Analytical expressions are derived for the BER, decision threshold and sensitivity penalty caused by the large IF bandwidth in coherent optical ASK receivers, with single filter IF detection and post-detection filtering. Results can be obtained without the use of computer simulations and are valid for single branch, polarisation and phase-diversity ASK receivers.
