Exact Outage Probability of Spectrum-Sharing DF Relaying with Transmit Antenna Selection
نویسندگان
چکیده
Considered is a spectrum-sharing network consisting of a primary user and a secondary decode-and-forward relaying system with a direct source-destination link, then a transmit antenna selection (TAS) scheme for the secondary relaying system are investigated over Rayleigh fading channels, and an exact closed-form expression for the outage probability are derived. Furthermore, Monte Carlo simulations are presented to confirm the analytical result, and show that the TAS scheme can also improve the diversity gain in the spectrum-sharing network.

Cooperative MIMO Relaying with Orthogonal Space-Time Block Codes in Wireless Channels with and without Keyholes
Cooperative multiple-input multiple-output (MIMO) relaying is investigated in the paper. We introduce DFAF selection MIMO relaying, where the relay equipped with multiple antennas can adaptively switch between decode-and-forward (DF) and amplify-and-forward (AF) according to its decoding state of the sourcemessage. We consider two wireless environment scenarios: 1)The scenario with traditional ...

In this paper, we deal with the performance analysis of full-duplex relaying in decode-&-forward cooperative networks with multiple-antenna terminals. More specifically, by analyzing the end-to-end statistics, we derive the accurate closed-form expressions of the end-to-end outage probability for both transmit and receive ZFBF scheme over Rayleigh fading environments. Some selected results show...

© 2014 ETRI Journal, Volume 36, Number 1, February 2014 http://dx.doi.org/10.4218/etrij.14.0113.0348 Recently, efficient partial relay selection (e-PRS) was proposed as an enhanced version of PRS. In comparing e-PRS, PRS, and the best relay selection (BRS), there is a tradeoff between complexity and performance; that is, the complexity for PRS, e-PRS, and BRS is low to high, respectively, but v...

The outage probability (OP) and average symbol error probability (ASEP) performance of multiple-mobile-relay-based mobile-to-mobile (M2M) networks with decode-and-forward (DF) relaying over N-Nakagami fading channels is investigated in this paper. The power allocation problem is formulated to determine how the overall transmit power should be shared between broadcasting and relaying phases for ...
