Soft Decode and Forward Improves Cooperative Communications
Mobile receivers can benefit from an increased spatial diversity through cooperation. Two relaying techniques are typically used : either Amplify and Forward (AF) or Decode and Forward (DF). This contribution presents a new technique which combines the main advantages of both AF and DF. This technique amounts to a DF scheme where all operations are performed in a soft-input soft-output fashion....
متن کاملPerformance Analysis of cooperative SWIPT System: Intelligent Reflecting Surface versus Decode-and-Forward
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...
متن کاملNetwork-Coding-based Adaptive Decode and Forward Cooperative Transmission in a Wireless Network: Outage Analysis
In cooperative transmission users are allowed to share antennas to transmit their messages to a common destination. Users employ either amplify-and-forward or decodeand-forward strategies to forward each others’ messages. In network-coding-based cooperative transmission schemes, users are allowed to combine their own and their partner’s message by a network-coding operation. This work analysis ...

متن کاملLiterature survey for Decoder Performance Analysis of Relay Based Decode-and-Forward Cooperative Diversity Network
--Performance degradation is an major problem in a relay based Decode-and-Forward (DF) receiving cooperative system. In the DF protocol , existing decoder performances have high decoding complexity, because destination require exact knowledge of the sourcerelay link along with the channel coefficient of source-destination and relay –destination links. In the proposed method, degradation can be ...
