Study Design: Comparative study by simulation in MATLAB software. Place and Duration of Study: Digital Communications Signal Processing (DCSP) Lab. of Shahid Rajaee Teacher Training University (SRTTU), Since 1 st June 2012 up to 1 st August 2014. Methodology: In the existing research works, relay-based system is modeled by a pair of transmitter-receiver nodes and a number of relays. Also, it is assumed that the selected relays are always free. In this investigation, the effect of relay occupancy due to other pairs is considered. For this purpose, a uniform distribution is applied for all relays to show the effect of free or busy relay nodes. Then, the performance of the relay selection methods is obtained by using two well-known performance metrics, bit error rate (BER) and outage probability. As the main goal of this research, a new approach is proposed which first finds the free relays and then applies one of the selectionRead More
