Outage probability of network-coding-based cooperative communication system

Relay users play a significant role in cooperative communication system improving the overall performance by increasing reliability. First, based on code division multiple access (CDMA) techniques, we propose a network coding (NC) based CDMA cooperation, which consumes less time slots in either synchronous or asynchronous transmission. Further, NC-based cooperative system saves transmission bandwidth, in other words, we show that it reduces outage probability as compared to the traditional cooperative communication system. These results are shown considering a Nakagami-m fading channel.
