Abstract
Network coding is a technique where the transmitted data is encoded and decoded to increase throughput, reduce delays and building a stronger network. Physical network coding (PNC) was originally proposed as a way to boost the performance of Network coding using electromagnetic waves. Cooperative communication aims to reduce fading multipath interference. Amplify and forward (AF) cooperative communications system is the information sent to the relay node will be strengthened and sent to the node destination. This article presents AF cooperative communication systems without and with network coding were implemented on Software Defined Radio module (SDR) was Wireless Open-Access Research Platform (WARP). Furthermore, the measurement of system performance is throughput of the system in indoor and outdoor environment at LOS and NLOS condition. Based on the results of measurement throughput of the system in the indoor environment indicated that cooperative communication system with network coding yield increase of 14% throughput without network at LOS condition and 20% at NLOS condition. While in the outdoor environment indicated increase of 16% throughput at LOS and NLOS condition.
