In this paper, we investigate the performance of free space optical (FSO) systems with a multiuser scheme employing select-max scheduling technique. Specifically, we consider an FSO communication system which employs a central node equipped with N transmit apertures, each of which aimed to any of the users. Under the assumption of log-normal turbulence channels, we derive closed-form outage capacity...
This paper presents a low-complexity iterative joint detection and decoding algorithm for finite geometry-low density parity check (FG-LDPC) coded multiple-input multiple-output (MIMO) systems, in which the MIMO channel detector and the FG-LDPC decoder iteratively exchange soft information. The key to the simplicity of the algorithm is the use of a bit flipping-based decoder for FG-LDPC code. An important...
In this letter, an improved bit-flipping decoding algorithm for high-rate finite-geometry low-density parity-check (FG-LDPC) codes is proposed. Both improvement in performance and reduction in decoding delay are observed by flipping multiple bits in each iteration. Our studies show that the proposed algorithm achieves an appealing tradeoff between performance and complexity for FG-LDPC codes.
