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 ... -
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 ... -
Flexible architecture of relay-based wireless network for network lifetime extension with hop-count constraint
(Informa Group, 2011)In relay-based wireless networks, messages need to be forwarded via intermediate relay mobile terminals (MTs). However, because of various transmission distances and unbalanced traffic load, some relay MTs may tend to drain ... -
Minimum power architecture of relay-based network with bandwidth and hop-count constraints
(Trans Tech Publications, 2011)Energy bills are on the rise and with the recent attention to saving the global environment. Saving energy (minimizing energy consumption) is becoming a standard issue for all industrial and commercial applications. Moreover, ... -
Peer-to-peer multipoint video conferencing with layered video
(Elsevier, 2011-01)A peer-to-peer (P2P) architecture for multipoint video conferencing using layered video coding at the end hosts is proposed. The system primarily targets end points with low bandwidth network connections and enables them ... -
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 ... -
Relay selection in dual-hop vehicular networks

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 ... -
Isovector axial-vector form factors of octet baryons in QCD
(American Physical Society, 2011-06-01)We compute the diagonal isovector axial-vector as well as induced pseudoscalar form factors of nucleon, Σ, and ≡ baryons by employing the light-cone QCD sum rules to leading order in QCD and including distribution amplitudes ... -
A novel pulse-positioned coding scheme for fiber fault monitoring of a PON

Preface
(Springer International Publishing, 2011-09)Developments in the field of wireless communications continue at an unabated pace. During the previous decade starting in the early 1990s, we have seen the introduction and mass market adoption of many different types of ... -
Tensor form factors of nucleon in QCD
(Elsevier, 2011-10-25)We extract the isovector tensor nucleon form factors, which play an important role in understanding the transverse spin structure of the nucleon when related to the quark helicity-flip generalized parton distributions via ... -
