    The Effect of Co-channel Interference in DF Based MARC System with Relay Selection
    (IEEE, 2017) Karabulut, Muhammet Ali; Aslan, Hayri; Ozdemir, Ozgur; Ilhan, Haci
    Network coding has recently received significant attention as an innovative approach to improve the throughput of wireless communication systems. The multiple access relay channel (MARC), in which multiple users communicate with a common destination via relays, is one of the important network coding applications for wireless cooperative communications. In this paper, the effect of co-channel interference in decode-and forward (DF) based MARC model with relay selection is investigated by obtaining the average bit error rate (BER) results of the proposed system for cascaded Rayleigh fading channels. The simulation results obtained by using binary phase shift keying (BPSK) modulation have shown that the proposed system overcome diversity gain reduction due to error propagation, and detrimental effects of the co-channel interference.

    Performance Analysis of C-MRC Technique in DF Based Cooperative System with Co-Channel Interference
    (IEEE, 2015) Aslan, Hayri; Ilhan, Haci; Ozdemir, Ozgur
    We have investigated the performance analysis of DF (Decode-And-Forward) based cooperative system using cooperative MRC (C-MRC) at the destination with co-channel interference in Rayleigh fading channels. The performance of C-MRC is compared with maximal-ratio combining (MRC) using the effective Signal to Interference plus Noise Ratio (SINR) of the system. It is seen that performance of C-MRC technique is much better than that of MRC. The Monte Carlo simulations are provided to illustrate the effect of interference on the performance where interference channels are independent and identically distributed.

    Virtual Noise Based Detection in Cooperative Systems with Co-Channel Interference
    (IEEE, 2016) Aslan, Hayri; Ilhan, Haci; Ozdemir, Ozgur
    In this paper, we have investigated the effect of cochannel interference on Decode-and-forward based cooperative communication system by providing the analytical results and computer simulations over Rayleigh fading channels. Virtual noise technique is used with co-channel interference at relay and destination terminals. It can be clearly observed that virtual noise techniques provides full diversity gain for proposed system. The accuracy of the analytical results shown by computer simulations.
