The Poisson multiple-access channel

A. Lapidoth, S. Shamai
1998 IEEE Transactions on Information Theory  
The Poisson multiple-access channel (MAC) models many-to-one optical communication through an optical fiber or in free space.  ...  We quantify the loss that is incurred when Time-Division Multiple Access (TDMA) is employed and show that while in the two-user case and in the absence of dark current the penalty is rather mild, the penalty  ...  D(t) is the dark-current Poisson process with rate 0 .

Channel capacity and maximum-likelihood detection for atmospherically disturbed binary photocounting communications (Corresp.)

R. Yen, P. Diament, M. Teich
1972 IEEE Transactions on Information Theory  
The noise arising from background radiation and from dark current in the photodetector is considered to be independent and noninterfering and therefore leads to a Poisson distribution [5].  ...  Background radiation and dark current have been taken into account. Curves are presented for the probability of error and the mutual information for varying levels of atmospheric turbulence.  ...  The noise arising from background radiation and from dark current in the photodetector is considered to be independent and noninterfering and therefore leads to a Poisson distribution [5] .  ...

Constellation Optimization for Phase-shift Keying Coherent States with Displacement Receiver to Maximize Mutual Information

Rahul Bhadani, Ivan B. Djordjevic
2020 IEEE Access  
Finally, we study the impact of dark current on the channel capacity. From our study, we observe that the higher the dark current, the lower the capacity gets.  ...  A comparison of the channel capacity with varying transmittivity for null and optimal displacement. For a particular τ , optimal displacement provides higher channel capacity.  ...  In addition to that, we also execute few simulation with random initial points and we find out that C G , the capacity comes out to be same with varying optimal values of priors and displacements (there  ...
