High-rate distributed space-time-frequency coding for wireless cooperative networks
(IEEE, 2011-02)
In this paper, we propose high-rate distributed space-time-frequency codes (DSTFCs) to exploit maximum achievable diversity gains over frequency-selective fading channels. The proposed designs achieve full-rate for any ...
A novel pulse-positioned coding scheme for fiber fault monitoring of a PON
(IEEE, 2011-09)
In this letter, we propose a novel optical coding scheme for fiber link quality monitoring of a passive optical network (PON). The proposed scheme named incrementally pulse positioned coding (IPPC) is practically very ...
Infrastructure-to-vehicle cooperative communications with decode-and-forward relaying
(IEEE, 2011)
In this paper, we consider infrastructure-to-vehicle cooperative communications in which roadside access points use vehicles as relaying terminals. This can be particularly useful in suburban or remote areas where the ...
Information theoretic performance of cooperative underwater acoustic communications
(IEEE, 2011)
Cooperative communication is considered as a major enabling technique to meet the demanding performance requirements of future underwater acoustic (UWA) communication systems. In this paper, we investigate the information ...
Cooperative inter-vehicular communications in highway traffic
(2011)
In this paper, we investigate the performance of a single relay assisted cooperative vehicular network in a highway traffic scenario. Source and relaying vehicles are assumed to be traveling in the same direction with ...
Relay selection in dual-hop vehicular networks
(IEEE, 2011-02)
In this letter, we investigate cooperative diversity with relay selection over cascaded Rayleigh fading channels. In particular, we analyze the performance of a relay selection scheme for cooperative vehicular networks ...
Outage analysis of Hybrid-ARQ protocols in coherent free-space optical communications
(IEEE, 2011)
In this paper, we investigate the performance of automatic retransmission request (ARQ) protocols in coherent free-space optical (FSO) communications. Specifically, we study the outage performance of three different ...
DMT analysis of multi-hop coherent FSO communication over atmospheric channels
(IEEE, 2011)
In this paper, we investigate the diversity-multiplexing tradeoff (DMT) of a multi-hop coherent free-space optical (FSO) system over atmospheric channels. We consider a relay-assisted FSO system with decode-and-forward ...
EM-based joint time delay and channel estimation for cooperative communications
(IEEE, 2011)
In this paper, we study joint time delay and channel estimation for a cooperative communication system with amplify-and-forward (AF) relaying. The proposed joint estimator is based on Expectation-Maximization (EM) algorithm ...
On the performance analysis of multirelay cooperative diversity systems with channel estimation errors
(IEEE, 2011-06)
In this paper, we investigate the performance of an amplify-and-forward (AF) cooperative diversity system with multiple relays in the presence of channel estimation errors. We consider both conventional relaying (in which ...
