Multipath-doppler diversity for broadband cooperative vehicular communications
(IEEE, 2011)
Initial works on cooperative vehicular communications build upon the assumption of frequency-flat and quasi-static fading channels. This can be justified only for narrowband systems in very slow traffic flows such as in ...
Moment generating function-based performance evaluation of amplify-andforward relaying in N∗Nakagami fading channels
(IEEE, 2011-02-11)
In this study, the authors investigate the error rate performance of amplify-and-forward relaying over N∗Nakagami fading channels. This is a recently introduced channel model that involves the product of N Nakagami-m-distributed ...
Spectrum trading for non-identical channel allocation in cognitive radio networks
(IEEE, 2011)
In this paper, we investigate spectrum trading via auction approach for cognitive radio networks. We consider a realistic valuation function in terms of different parameters for secondary users (SUs), and propose an efficient ...
Formulations and branch-and-cut algorithms for the generalized vehicle routing problem
(Informs, 2011-08)
The generalized vehicle routing problem (GVRP) consists of finding a set of routes for a number of capacitated vehicles on a graph where the vertices are partitioned into clusters with given demands, such that the total ...
Multicarrier HF communications with amplify-and-forward relaying
(IEEE, 2011)
High-frequency (HF) radio communication has been recognized as the primary means for long-range wireless communications since the advent of radio. With its unique features, HF communication continues to be used for a wide ...
Combining haar feature and skin color based classifiers for face detection
(IEEE, 2011)
This paper presents a hybrid method for face detection in color images. The well known Haar feature-based face detector developed by Viola and Jones (VJ), that has been designed for gray-scale images is combined with a ...
Cooperative BICM-OFDM systems for frequency-selective relay channels
(IEEE, 2011)
In this paper, we consider a cooperative multi-carrier multi-relay system over frequency-selective fading channels. Specifically, we adopt the orthogonal frequency division multiplexing (OFDM) with bit-interleaved ...
Performance evaluation of multiple-bit delay detection with majority vote decision rule in optical DPSK systems
(IEEE, 2011)
In this paper, the performance of multiple-bit delay detection (MBDD) systems in optical differential phase shift keying (DPSK) is investigated. Assuming that the dominant noise in the system is originated by the optical ...
Multi-hop relaying over the atmospheric poisson channel
(IEEE, 2011)
In this paper, we study the outage behavior of a decode-and-forward multi-hop free-space optical (FSO) system over a Poisson channel degraded by atmospheric turbulence. We assume that perfect channel side information (CSI) ...
Guiding architects in selecting architectural evolution alternatives
(Springer Science+Business Media, 2011)
Although there exist methods and tools to support architecture evolution, the derivation and evaluation of alternative evolution paths are realized manually. In this paper, we introduce an approach, where architecture ...
