| Abstract(in English) | Collaborative decoding attracts much attention for improving the quality of received signal in wireless broadcasting for mobile communication. Incremental-Maximum Ratio Combining (I-MRC) is one of the conventional collaborative decoding methods. In I-MRC, the node having best quality-received signal makes the request of transferring the information signal from the node having the next best quality-received one. In the broadband wireless communication, the transmitted signal suffers from the frequency selective fading and thus in I-MRC, the significantly attenuated frequency spectrum components of information signal are also transferred to the best quality user. Therefore, these are the bottle neck for improving quality. In this paper, the collaborative decoding based on the method of block cooperation is proposed in OFDM system. In the proposed technique, the sharing of the significantly attenuated frequency spectrum components is avoided. In addition, for reducing the amount of exchanging pre-information (channel state information: CSI), the self selection of resource block is proposed. The effect of proposed collaborating technique is shown by computer simulation. |
