Symbol-Error Probabilities for Pulse-Position Modulation Signaling With an Avalanche Photodiode Receiver and Gaussian Thermal Noise
نویسندگان
چکیده
The calculation of symbol-error probabilities for uncoded pulse-position modulation using a Webb-modeled avalanche photodiode receiver in the presence of additive Gaussian thermal noise is discussed. Performance curves for 256-ary pulseposition modulation obtained through Monte Carlo simulation as well as a numerical upper bound are presented. The Webb-plus-Gaussian model for the distribution of the received signal is compared with the much simpler Gaussian-only approximation. Results are presented for both fixed and optimized values of the avalanche photodiode gain parameter.

Performance of the Optimum Receiver for Pulse-Position Modulation Signals With Avalanche Photodiode Statistics
Statistical modeling of the avalanche photodiode electron output is discussed. The exact McIntyre–Conradi density function for the output electron count is reviewed, along with the Webb and Gaussian approximations. In addition, the maximum-likelihood decision statistic for detection of pulse-position-modulation (PPM) signals is derived using the more accurate Webb density rather than the Poisso...

متن کاملThe Capacity of Avalanche Photodiode-Detected Pulse-Position Modulation
The capacity is determined for an optical channel employing Pulse Position Modulation (PPM) and an Avalanche PhotoDiode (APD) detector. This channel is different from the usual optical channel in that the detector output is characterized by a Webb-plus-Gaussian distribution, not a Poisson distribution. The capacity is expressed as a function of the PPM order, slot width, laser dead time, averag...
متن کاملReceiver Structure and Performance for Trellis-Coded Pulse-Position Modulation in Optical Communication Systems
This article describes a receiver structure for trellis-coded pulse-position modulation (T-PPM) for optical communication systems. Monte Carlo simulation results of the Viterbi decoding algorithm under realistic Webb modeling of the avalanche photodiode (APD)-based receiver are compared with asymptotic bounds on performance. These results show that T-PPM can reduce the loss in performance incur...
