Practical Partial Decode and Forward Encoding Scheme for Relay Channel
In this paper, a source-destination pair, which is augmented by a half-duplex relay, is considered. Two practical partial decode and forward encoding schemes are proposed. In these transmission schemes, the relay may decode the source's signal either partially or completely. In each encoding technique, twophase transmission scheme is developed in which the relay can partially listen to the sour...
متن کاملOptimum Power Allocations for Fading Decode-and-Forward Relay Channel
Abstract—In this paper optimum power allocations are derived for a fading decode-and-forward full-duplex relay channel, analytically. Individual power constraints for the source and the relay are assumed and the related optimization problem is analyzed for two scenarios. First, optimization is taken over the source power, the relay power, and the correlation coefficient between the transmitte...
متن کاملThe Scheme of Power Allocation for Decode-and-Forward Relay Channel in Energy Harvesting WSNs
Recently, the issue of excessive energy consumption in wireless communications has become increasing critical, and the energy harvesting as a renewable energy resource, has received extensive attractions. In this paper, a wireless sensor network (WSN) is considered, where the source-destination pair communicates via an energy harvesting relay links. We study the problem of the harvested energy ...
متن کاملThe Optimal Input Distribution for Partial Decode-and-Forward in the MIMO Relay Channel
This paper considers the partial decode-and-forward (PDF) strategy for the Gaussian multiple-input multiple-output (MIMO) relay channel. Unlike for the decode-and-forward (DF) strategy or pointto-point (P2P) transmission, for which Gaussian channel inputs are known to be optimal, the input distribution that maximizes the achievable PDF rate for the Gaussian MIMO relay channel has remained unkno...
متن کاملPerformance of Selective Decode - and - Forward Relay Networks with Partial Channel Information
Relay selection is an attractive method to improve the bandwidth efficiency of cooperative networks [1]-[3]. Specifically, Bletsas and others [1] proposed a distributed relay selection based on the channel information of both the first and second hops for each relay, showing that the diversitymultiplexing tradeoff of relay selection is identical with that of distributed space-time coding. Recen...
