Outage Probability and Power Allocation for Two-Way DF Relay Networks with Relay Selection
In this paper, we investigate the outage probability and power allocation for the two-way decode-andforward (DF) relay networks with relay selection. Specially, we consider independent but not necessarily identical distributed Rayleigh fading channels. Firstly, we derive an exact closed form outage probability expression. To shed light on the relation between the outage probability and the powe...
متن کاملPower Allocation In Cooperative Relay Channels
This paper concerns power allocation in relay-assisted wireless channels for two-hop transmission. First, the transmitter sends the information to both the relay and receiver parts. Next, in the second hop, the transmitter cooperates with the relay to increase the received signal to noise ratio (SNR), assuming the relay makes use of the Amplify and Forward (AF) strategy. Moreover, it is assumed...
متن کاملPower Allocation for Relay-Assisted Indoor Power Line Communication Systems
Using the worldwide already existing power lines as a communication medium for local area networking (LAN) has received much interest for many indoor information sharing applications. However, the indoor power line communication (PLC) channels demonstrate hostile characteristics for broadband signal transmission. A lot of efforts have been made in order to apply some advanced technologies, whic...
متن کاملService outage based power and rate allocation
This paper explores a spectrally efficient, variable rate transmission scheme under a service outage constraint for a block fading channel model. The service outage constraint is motivated by real time variable rate applications. In a service outage, the transmission code rate is below a given basic rate and may in fact be zero. Unlike an information outage in the capacity versus outage problem...
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...
