Paper Abstract

The present work deals with the performance analysis of an optical FSI( heterodyne receiver einpioying limiter-discriminator detection ( LDD). The analysis is carried out with due considerations to laser phase noise and FM clicks at discriminator output. The receiver performance is assessed from the plots of bit error probability (BEP) versus IF SNR for various combinations of IF bandwidth frequency deviation az laser Jinewidth. The results indicate that an optical heterodyne FSK receiver employing LDD can achieve a BEP floor for suttable combinations of IF banawidth arid frequency deviations with moderate laser linewidths ( 5/. ). This suggests an easier implementation of NCFSK heterodyne optical receivers with a reasonaDie tolerance to the laser phase noise. I.
