ABSTRACT:
Received signals of the respective sub-carriers are multiplied by a weighting controlled for each sub-carrier, using a weighting control part2-8and multipliers2-9,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.
