Outage Probability of Decode - and - Forward Relaying Systems with Efficient Partial Relay Selection in Nakagami Fading Channels
© 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...
متن کاملOpportunistic Relay Selection for Decode-and-Forward Two-Way Relaying under Outdated Channel State Information
—The Channel State Information (CSI) plays a significant role in wireless Relay Selection (RS) systems. Due to the time variation of channels, the CSI in the data transmission phase may differ (i.e., is outdated) from that in the relay selection phase. Addressing this issue, the Decode-andForward (DF) Two-Way Relaying (TWR) network is considered, and the impact of outdated CSI on the system pe...
متن کاملFinite-SNR analysis for partial relaying cooperation with channel coding and opportunistic relay selection
This work studies the performance of a cooperative network which consists of two channel-coded sources, multiple relays, and one destination. To achieve high spectral efficiency, we assume that a single time slot is dedicated to relaying. Conventional network-coded-based cooperation (NCC) selects the best relay which uses network coding to serve the two sources simultaneously. The bit error rat...
متن کاملError performance of two-hop decode and forward relaying systems with source and relay transmit antenna selection
ELECT The error performance of two-hop cooperative communication (CC) systems with transmit antenna selection (TAS) at the source and relay over η− μ fading channels is analysed. The probability density function of the received signal-to-noise ratio and the average bit error rate of two-hop CC systems with a source-destination direct link and TAS at both the source and the relay is derived. The...
متن کاملOutage Performance of Decode-and-Forward in Two-Way Relaying with Outdated Channel State Information
In this paper, we analyze the outage behavior of decode-and-forward relaying in the context of selective two-way cooperative systems. First, a new relay selection metric is proposed to take into consideration both transmission rates and instantaneous link conditions between cooperating nodes. Afterwards, the outage probability of the proposed system is derived for Nakagami-m fading channels in ...
