| Abstract(in English) | On a relay channel, the collaborative (or cooperative) communications with the superimposition of information can improve its performance. In general, the system can improve the performance in proportion to the available relay nodes. However, it is not realistic for the system with the superimposing techniques to expand to the case of three or more relay nodes, since the optimum design (rate or power allocation) becomes very difficult and the decoding complexity is un feasible. To mitigate above problem, we have previously proposed a cooperative communication technique utilizing an multilevel coded modulation, which named as multilevel coded cooperation. With the multilevel coded cooperation, the system can easily expand to the case of arbitrary number of cooperative nodes with feasible computational complexity. However, the previous works have focused only on the theoretical design and analyses (outage analyses). In this work, we implement the proposed multi-level coded cooperation and evaluate its Frame Error Rate (FER) performances. From the computer simulations results, the multilevel coded cooperation, in the case when the number of relays is two and the type of modulation is 8PAM, can obtain a maximum diversity gain and achieve good FER performance. |
