<P>PROBLEM TO BE SOLVED: To achieve peak power reduction in MIMO multiplexing with precoding while suppressing degradation in transmission quality as much as possible. <P>SOLUTION: The MIMO multiplex transmission method includes: a step of generating transmission data corresponding to a plurality of streams transmitted simultaneously; a step of precoding the transmission data so that the respective pieces of transmission data are received orthogonally in a receiver; a step of suppressing the peaks of transmitted electric power as a whole by clipping the amplitude in the unit of a stream for each piece of transmitted data after precoding is carried out; and a step of suppressing the allocation of interference electric power which is caused by the amplitude clipping to streams in a good channel state. <P>COPYRIGHT: (C)2011,JPO&INPIT |
