Practical Partial Decode and Forward Encoding Scheme for Relay Channel
نویسنده
چکیده
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 source in the first phase until it can generate the source’s message and then, in the second phase, forward it to its destination. By employing these transmission phases, the achievable rates are obtained . Rigorous numerical examples are presented to i) show the value of power allocation between the source and the relay, and ii) optimize the length of the listening phase.

In this paper, power efficiency (PE) of a relay interference channel including multiple transmitter nodes, multiple relay nodes and multiple destination is investigated. It is assumed that the destination and transmitter nodes are equipped with a few number of antennas but the relay nodes have a large number of antennas.

In this paper, we explore the impacts of utilizing intelligent reflecting surfaces (IRS) in a power-splitting based simultaneous wireless information and power transfer (PS-SWIPT) system and compare its performance with the traditional decode and forward relaying system. To analyze a more practical system, it is also assumed that the receiving nodes are subject to decoding cost, and they are on...

We investigate the superposition strategy and its usefulness in terms of achievable information theoretic rates. The achievable rate of the superposition of block Markov encoding (decode-forward) and side information encoding (compress-forward) for the three-node Gaussian relay channel is analyzed. It is generally believed that the superposition can out perform decode-forward or compress-forwar...

Based on the analysis and simulation resultsprovided in this paper, the proposed method has bettertransmission time than the scheme which only the relay ...
متن کاملCoding Schemes for the Two-Way Relay Channels
In modern transmission networks, relay plays an important role for cooperative strategies. Several relaying strategies, such as decode-forward, compress-forward and amplify-forward, have been proposed for relay channels and networks. However, the capacity for the general relay channel and network is still unknown. In this thesis, we propose several relay schemes for different relay models. In t...
