| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The cooperative communication attracts the attention for mobile communication system. In the cooperative communication, each user transmits the partnership user for sending the own data symbol to the base station through the partnership user station. As a result, some paths for sending the data are made so that the transmit diversity can be established. In the conventional cooperative communication, the partner user detects whether the received symbol includes any erroneous bits or not with the cyclic redundancy check (CRC). If any erroneous bits are not included, since the user transmits the partnership user's data to the base station, transmit diversity gain can be obtained. Otherwise, since the user transmits the own data to the base station, the transmit diversity gain cannot be obtained. In addition, in the conventional cooperative communication, each user must inform the CRC result to the base station. In this paper, we propose a novel cooperative method. In the proposed system, if the CRC detects the erroneous bits from the received data, the user transmits the soft decided symbol obtained from the decoding processing. From the computer simulation, the proposed cooperative communication can achieve the better error rate performance than the conventional one due to obtaining the transmit diversity gain continuously. | |
