OFDM TRANSMITTER-RECEIVER AND OFDM TRANSMISSION- RECEPTION METHOD

摘要

PROBLEM TO BE SOLVED: To suppress peak voltage without deteriorating error rate characteristics and without reducing transmission efficiency. SOLUTION: In the case a reception power difference is larger than a prescribed value and it is required to inert a signal to suppress peak power, a connection switch 301 is closed, based on a control signal A1. A changeover switch 106 is controlled so as to transmit a transmission signal from an optimum antenna branch and a changeover switch 302 is controlled so that a connection destination of a changeover switch 302 differs from that of the changeover switch 106 and an open antenna branch transmits a signal to suppress the peak power.
