TRANSMITTING METHOD AND TRANSMITTING APPARATUS IN OFDM-CDMA COMMUNICATION SYSTEM

摘要

A OFDM-CDMA communication system that generates a plurality of subcarrier components by multiplying each of a plurality of transmission symbols by a channelization code whose length is N according to a spreading factor, and transmits those subcarrier components by a plurality of different subcarriers, measures the propagation environment of each subcarrier, divides the subcarriers into groups having N number of subcarriers in each group whose propagation environments are close one another, and transmits the N number of subcarrier components, which have been multiplied by the channelization code, by subcarriers of the same group.
