MULTI-CARRIER CDMA TRANSMISSION SYSTEM AND TRANSMISSION METHOD

摘要

A multi−carrier transmission for multipying transmission data by each of the codes constituting orthogonal codes and transmitting the products through a predetermined subcarrier. A plurality of different subcarriers are exclusively assigned to the users. The users multi−carrier transmit the transmission data through the assigned subcarriers. Moreover, a base station assigns a plurality of different subcarriers exclusively to the users and conducts a transmission beam forming thereby to multi−carrier transmit the transmission data through the assigned subcarriers to the users.
