Optimal 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 کاملAmplify-forward relaying for multiple antenna multiple relay networks under individual power constraint at each relay
This article considers the design of an optimal beamforming weight matrix of multiple-antenna multiple-relay networks. It is assumed that each relay utilizes the amplify and forward strategy, i.e., it multiplies the received signal vector by a matrix, dubbed the relay weight matrix, and forwards the resulting vector to the destination. Furthermore, we assume that the source and the destination ...
متن کاملCapacity Scaling Laws in Asynchronous Relay Networks
This paper examines capacity scaling in asynchronous relay networks, where L single-antenna source-destination terminal pairs communicate concurrently through a common set of K single-antenna relay terminals using one-hop relaying. In the perfectly synchronized case, assuming perfect channel state information (CSI) at the relays, the network capacity is known [1] to scale (asymptotically in K f...
متن کاملOptimal Relay Power Allocation for Amplify-and-Forward Relay Networks with Non-linear Power Amplifiers
In this paper, we propose an optimal relay power allocation of an Amplify-and-Forward relay networks with nonlinear power amplifiers. Based on Bussgang Linearization Theory, we depict the non-linear amplifying process into a linear system, which lets analyzing system performance easier. To obtain spatial diversity, we design a complete practical framework of a non-linear distortion aware receiv...
متن کاملEfficient Antenna Selection for Amplify-and-Forward Two-Way MIMO Relay Systems
In this letter, we propose an efficient relay antenna selection algorithm for the amplify and forward (AF) two-way multipleinput multiple-output (MIMO) relay systems with analogue network coding (ANC). The proposed algorithm greedily selects the additional receivetransmit antenna pair that provides the maximum sum-rate. An iterative computation method is also designed to evaluate the sum-rate e...
