Performance Analysis of Wireless Cooperative Networks with Iterative Incremental Relay Selection
In this paper, an iterative incremental relay selection (IIRS) scheme is considered for wireless cooperative networks in order to increase the reliability of transmission. Different from the conventional incremental relay selection which incrementally selects a best relay for only one iteration; the IIRS scheme iteratively applies the incremental relaying and relay selection processes. To evalu...

JOINT SPATIAL-TEMPORAL SPECTRUM SENSING AND COOPERATIVE RELAYING FOR COGNITIVE RADIO NETWORKS Tuan T. Do, PhD George Mason University, Spring, 2011 Dissertation Director: Dr. Brian L. Mark The number of wireless systems and services has grown tremendously over the last two decades. As a result, the availability of wireless spectrum has become extremely limited. Cognitive radio is a new techniqu...
متن کاملEffects of Channel Estimation on Multiuser Virtual MIMO-OFDMA Relay-Based Networks
A practical multiuser cooperative transmission scheme denoted as Virtual Maximum Ratio Transmission (VMRT) for multipleinput multiple-output-orthogonal frequency division multiple access (MIMO-OFDMA) relay-based networks is proposed and evaluated in the presence of a realistic channel estimation algorithm and using low-density parity-check (LDPC) codes. It is shown that this scheme is robust ag...
متن کاملExploiting New Forms of Multiuser Diversity in Spectrum Sharing Cognitive Radio Networks
Multiuser diversity (MD), as a fundamental property of fading wireless networks, has been widely applied in today’s wireless communication systems. In this letter, we consider the newly emerging cognitive radio (CR) wireless network that communicates by sharing the spectrum with the existing primary radio (PR) network. Under the assumption that the CR transmit terminal protects the PR transmiss...
متن کاملExploiting New Forms of Multiuser Diversity for Spectrum Sharing in Cognitive Radio Networks
Multiuser diversity, as a fundamental property for fading wireless networks, has been widely applied in today’s wireless communication systems. Conventionally, due to the multiuser diversity, the long-term throughput of a wireless system consisting of multiple independently fading communication links can be enhanced by selecting one link with the best instantaneous channel quality to transmit a...
