Mach-Zehnder modulators introduce nonlinearities for large driving signals that induce bit error rate (BER) penalties. In silicon photonics a nonlinear phase response leads to a more complex nonlinear response. We propose a digital pre-distorter based on a nonlinear memory polynomial model to reduce BER penalty.
In this study, the authors consider a multiuser multiple-input multiple-output (MU-MIMO) free space optical (FSO) communication system and investigate the performance of various scheduling protocols which provide different degrees of tradeoff between throughput and fairness. In the MU-MIMO FSO system under consideration, the central node and each user node are equipped with multiple transmit and receive...
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...
In this paper, we investigate the performance of free space optical (FSO) systems with parallel multihop relaying and path selection. Specifically, we consider an FSO communication system which employs M parallel relaying paths each of which consists of N decode-and-forward relays. We assume the deployment of the so-called mth best path selection (m-BPS) protocol. In this protocol, data is transmitted...
