Performance Enhancement of Wireless Networks Using Cooperative Diversity Techniques

Abstract

Channel weakening is one among the significant issues in wireless communication which can
be overcome by the exploiting diversity gain, achieved via cooperation between nodes and
relays. In order to improve the gain, generally, we require more than one transmitting
antenna in a node, which is not too common due to the limits in size and complexity of
wireless mobile devices. Anyway by offering reception apparatuses to other single-receiving
wire hubs in a multi-client condition i.e., agreeable decent variety, a virtual multi-radio wire
cluster is framed and transmit-assorted variety is cultivated. In our proposed work, a network
containing a sender, a destination and a fixed relay, is analyzed with modified cooperative
diversity scheme such as Amplify-Quantize and Forward (AFQ) and compared with existing
cooperative communication protocol i.e., Amplify and forward (AF). Moreover the
performance of the proposed work is evaluated in terms of Bit-Error Rate, SNR and Outage
Probability.
