Compress and Forward Cooperative Relay in Device-to-Device Communication with and without Coding Techniques

Abstract

Today, spectrum utilization problem is controlled by using Device to Device (D2D) communication systems. Also, cooperative relay networks play an important role in interference reduction during any communication system, so this paper addresses the Compress and Forward (CF) cooperative relay network using different code techniques with D2D communication in the cellular spectrums. Simulation results will illustrate that outage ratio is reduced with 1.3 dB SNR improvements using coded CF than using non decoded CF. Moreover, comparison between our proposed protocol and pervious protocols like Decode and Forward (DF) will be made, resulting in bit error rate reduction with SNR gain equals to 10 dB.
