Multi-carrier CDMA transmission system, transmitting apparatus and receiving apparatus used in this system, and multi-carrier CDMA transmission method |
摘要 |
Received signals of the respective sub-carriers are multiplied by a weighting controlled for each sub-carrier, using a weighting control part 2 - 8 and multipliers 2 - 9, so that the mean square error between the signals following despreading and the signals that are actually transmitted is minimized. Afterward, MMSE combining is performed. |
