Performance analysis of MIMO cognitive amplify-and-forward relay networks with orthogonal space-time block codes
In this paper, we study the performance of multiple-input multiple-output cognitive amplify-and-forward relay networks using orthogonal space–time block coding over independent Nakagami-m fading. It is assumed that both the direct transmission and the relaying transmission from the secondary transmitter to the secondary receiver are applicable. In order to process the received signals from thes...
متن کاملOptimal Power Management to Minimize SER in Amplify and-Forward Relay Networks
This paper studies optimal power allocation to minimize symbol error rate (SER) of amplify-and-forward cooperative diversity networks. First, we analytically solve optimal power allocation problem to minimize SER for three different scenarios, namely, multi-branch single-relay, single-branch multi-relay and multi-branch multi-relay cooperative diversity networks, all subject to a given total re...
متن کاملAnalysis and Design of Distributed Space-Time Trellis Codes With Amplify-and-Forward Relaying
We study the asymptotic behavior of a cooperative scheme operating in amplify-and-forward (AF) mode when the number of relay terminals tends to infinity. We consider three time-division-multiple-access-based cooperation protocols which realize different degrees of broadcasting and receive collision. Optimal design rules for distributed space–time codes (STCs) are derived through the investigati...
متن کاملRateless Coding over Wireless Relay Networks Using Amplify/Decode and Forward Relays
In this paper two different rateless transmissionschemes are developed. In the proposed scheme, relay node candecode and forward the message to the destination if they areable to decode it, or amplify and forward the message to thedestination. Based on the analysis and simulation resultsprovided in this paper, the proposed method has bettertransmission time than the scheme which only the relay ...
متن کاملDistributed Space-Time Block Coding for Amplify-and- Forward Cooperative Networks
A robust way to combat multipath fading phenomena in wireless communications is to implement diversity techniques. Diversity is achieved by providing the receivers multiple independent replicas of the same information-bearing symbols through space, time, or frequency. Recently, a new type of diversity, so-called cooperative diversity, has been proposed in order to provide diversity when the wir...
