Performance analysis of decode and forward cooperative diversity networks with threshold scheme
Cooperative diversity technique is used for achieving high data rate and low BER with low transmit power. The paper proposes a new scheme for selection of first relay having SNR above a predefined threshold level in cooperative diversity network, based on geometric distribution. Closed form expression for outage probability is derived for independent and identically distributed channels with de...
متن کاملPerformance Analysis of Decode-and-Forward Protocols in Unidirectional and Bidirectional Cooperative Diversity Networks
Cooperative communications have the ability to induce spatial diversity, increase channel capacity, and attain broader cell coverage with single-antenna terminals. This thesis focuses on the performance study of both unidirectional and bidirectional cooperative diversity networks employing the decode-and-forward (DF) protocol. For the unidirectional cooperative diversity network, we study the a...
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 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 ...
متن کاملAdaptive Decode-and-Forward Cooperative Networks with Limited Feedback
We analyze the performance of an adaptive communication scheme in which by employing limited feedback, the source will decide to transmit signal to the destination either by the direct link or by the direct and relaying links. Specifically, by using the instantaneous SNR as the metric, if the S-D link is better, the source will transmit to destination directly. Otherwise, the two-phase transmis...
