The error characteristics of a free-space optical (FSO) channel are significantly different from the fiber based optical links and thus require a deep physical understanding of the propagation channel. In particular different fog conditions greatly

Indoor diffuse optical intensity channels are bandwidth constrained due to the multiple reflected paths be- tween the transmitter and the receiver which cause consider- able inter-symbol interference (ISI). The transmitted signal amplitude is inheren

Capacity of a radio relay channel has been extensively studied. Although general solution to the capacity problem is still elusive, solution for a physically degraded relay channel is available. This paper presents the original results for lower and

In the following paper we propose a new approach for extracting soft values from Mth order pulse position modulation (M-PPM). A new low-complexity algorithm is developed, where soft information for each data bit is calculated based on the power recei
