Capacity, Cutoff Rate, and Coding for Direct-Detection Optical Channel
It is shown that Pierce’s pulse-position modulation scheme with 2L pulse positions used on a self-noise-limited direct-detection optical communication channel results in a 2L-ary erasure channel that is equivalent to the parallel combination of L completelycorrelated binary erasure channels. The capacity of the full channel is the sum of the capacities of the component channels, but the cutoff ...

متن کاملError Exponents for a Direct Detection Optical Channel
Error exponent bounds for a noise free optical channel using a direct detection receiver are computed for the cases of Pulse Position Modulation (PPM) and for the basic channel with binary output and average intensity constraint. Some consequences are derived regarding the behavior of the interleaving scheme suggested by Massey, the optimality of the PPM format and the significance of the Ro pa...
متن کاملChannel capacity and error exponents of variable rate adaptive channel coding for Rayleigh fading channels
We have evaluated the information theoretical performance of variable rate adaptive channel coding for Rayleigh fading channels. The channel states are detected at the receiver and fed back to the transmitter by means of a noiseless feedback link. Based on the channel state informations, the transmitter can adjust the channel coding scheme accordingly. Coherent channel and arbitrary channel sym...
متن کاملOn the Capacity Region of the Intensity-Modulation Direct-Detection Optical Broadcast Channel
The capacity of the intensity-modulation direct-detection free-space optical broadcast channel (OBC) is investigated. The Gaussian model with input-independent Gaussian noise is used, with both average and peak intensity constraints. An outer bound on the capacity region is derived by adapting Bergmans’ approach to the OBC. Inner bounds are derived by using superposition coding with either trun...
