ABSTRACT:
An object of the present invention is to provide a method for suppressing peak power at a high encoding rate in a multi-carrier transmission system.The present invention provides a transmitter for transmitting a multi-carrier signal, in which when generating 128 patterns used to suppress the peak power of 8-bit sub-carrier mapping signals from 7-bit information bits in a encoding unit9, a sub-carrier generation unit11, for example, divides the signal point of QPSK modulation into orthogonal groups, generates a sub-carrier mapping signal in which a part of sub-carriers is dependent on the signal point of another sub-carrier and a receiver for receiving such a multi-carrier signal.
