Performance analysis of Amplify Quantize and Forward Relaying in Network Coded based system at various relay locations

摘要

This paper examines the performance of Network Coded (NC) based cooperative network for different relays location over Rayleigh fading channels. The comparisons of Amplify Quantize and Forward (AQF), Amplify and Forward (AF), Decode and forward (DCF) and Detect and Forward (DTF) protocols for the proposed system are explained. The relays performance in AQF, AF, DCF and DTF is studied in terms of Bit Error Rate (BER) vs Signal to Noise Ratio (SNR). Matlab software is used to build Monte-Carlo link level simulation. The effect of relays at different position in Rayleigh flat fading channel along with Additive White Gaussian noise is studied. BPSK modulation scheme is used for the transferring information.
