Closed-form suboptimal maximum-likelihood sequence detection for free-space optical communications.

Abstract

In this paper, a closed-form suboptimal maximum-likelihood sequence detection (MLSD) metric and its low-complexity version are proposed for free space optical communications systems operating over lognormal fading and high signal-to-noise channel. This algorithm provides a simplification to the algorithm reported by Riediger et al. In comparison, firstly… (More)
