Wireless communication system requires a higher data rate and a more robust transmission link between source and destination against noise and multipath fading effect while keeping a good quality of service. A cooperative communication system utilizing OFDM is considered an effective technology to enhance system performance. By taking advantages of cooperative diversity utilizing relays, this paper investigates the performance of the cooperative system with coded OFDM over two types of a cooperative protocol such as Decode and Forward (DF) and Amplify and Forward (AF),) utilizing Hierarchical modulation. The main goal of this work is to integrate the hierarchical modulation (HM) with cooperative communication focusing on unequal degradation of the two data streams transmitted on the direct link between source and destination and in-direct link through the relay. The main idea is to use different constellations order at the relay and destination according to the difference of SNR values. Using different constellations enhances system flexibility and manipulate this difference to improve the system performance For a relay network with one source, one relay, and one destination the BER performance is investigated when coded cooperative system employs HM over Rayleigh fading channel with OFDM system with distributed convolutional code. Simulation results showing that the proposed cooperative Coded OFDM system with Hierarchical modulation outperforms the reference system (Cooperative DF coded OFDM with MRC) with 3dB at . Also, the proposed system outperforms (Cooperative coded OFDM with EGC) with 5 dB at BER. Moreover, simulation results show that the proposed system outperforms (Cooperative AF coded OFDM with MRC) with about 4dB at BER.
