On the Use of Gaussian Approximation in Analyzing the Performance of Optical Receivers
IEEE Photonics Journal, 2014 The analytical calculation of the bit error rate (BER) of digital optical receivers that employ avalanche photodiodes (APDs) is challenging due to 1) the stochastic nature of the avalanche photodiode's impulse-response function and 2) the presence of ...

Data-Aided Versus Blind Single-Carrier Coherent Receivers
IEEE Photonics Journal, 2010 Fiber-optic research in signal processing for the first generation of coherent communication systems was dominated by receivers with blind adaptation. Next-generation systems will require a scalable and modular design for higher order modulation formats.
