Power minimization for OFDM modulated two-way amplify-and-forward relay wireless sensor networks
This paper studies a power minimization problem of an orthogonal frequency-division multiplexing modulated two-way amplify-and-forward relay wireless sensor network (WSN). The objective is to develop effective strategies for controlling the transmit power levels of WSN nodes and assigning the bit rates among different subcarriers to minimize the overall transmit power of the network, while ensu...
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 کاملCooperative beamforming for OFDM-based amplify-and-forward relay networks
In this paper, we investigate the cooperative beamforming (BF) design problem for amplify-and-forward relay networks over frequency-selective channels. Orthogonal frequency division multiplexing (OFDM) transmission is employed to resist the multipath effects. We focus on the time-domain (TD) BF due to the lower implementation complexity and less feedback requirement from the destination to perf...
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 کاملPower Allocation Strategies in Block-Fading Two-Way Relay Networks
This paper aims at investigating the superiority of power allocation strategies, based on calculus of variations in a point-to-point two-way relay-assisted channel incorporating the amplify and forward strategy. Single and multilayer coding strategies for two cases of having and not having the channel state information (CSI) at the transmitters are studied, respectively. Using the notion of cal...
