| Abstract(in English) | Coded cooperation has been proposed to simultaneously obtain spatial diversity and coding gain for multiple access channel (MAC) which consists of multi source nodes and common destination node. In coded cooperation, source nodes share information and distributedly encode parity from shared information. Spatially coupled repeat-accumulate coded cooperation (SC-RA-CC) is one based on spatially coupled repeat-accumulate codes and it is theoretically shown that SC-RA-CC achieves extraordinary high coding gain when the codeword length is infinite. In practice, however, SC-RA-CC cannot obtain the theoritical coding gain due to the finite packet length. In this paper, we propose distributed multi-dimensional spatially coupled repeat-accumulate codes which achieve higher coding gain even with the short packet length. The performance of proposal scheme is investigated via density evolution and computer simulations. |
