    摘要: A time slot which is formed by time-division multiplexing is divided into a plurality of blocks in at least a frequency direction, and also within each one of said plurality of blocks a plurality of subcarriers are formed. A predetermined number of plurality of blocks forms one communication channel, whereby a plurality of communications are formed within a time slot. With this, one time slot can be multiplexed by communication of multiple carriers separated in frequency. In this manner, with simple constitution, communication can be performed satisfactorily even in an environment where a multiple path is present.
