Abstract
In this paper, we study the channel capacity of discrete memoryless thresholding channels (DMTCs) that are used in Pulse Amplitude Modulation (PAM) for LED free-space transmissions. Although capacities of discrete memoryless channels (DMC) are well-studied and can be determined by various algorithms, the capacity of a DMTC is less explored and its capacity is more difficult to obtain. This is due to the fact that, unlike a typical DMC channel whose the capacity is a function input distribution, the capacity of a DTMC channel is a function of both input distribution and decision thresholds. To resolve this problem, we propose an algorithm for finding the channel capacity of a DMTC. Both theoretical and numerical results are provided to verify our approach.
