Abstract :
A recently reported ASK heterodyne system experiment has been analysed using a comprehensive theoretical model including the effects of laser phase noise, receiver noise, IF bandwidth, postdetection filtering and noise statistics following nonlinear demodulation and linear filtering. The excellent agreement between the theory and the quite independent experiment results lends strong support to our models for the effects of laser phase noise and filtering of non-Gaussian processes.
