TRANSMISSION SYSTEM, TRANSMISSION METHOD, TRANSMISSION APPARATUS, AND ELECTRONIC RECORDING MEDIUM HAVING RECORDED THEREIN TRANSMISSION PROGRAM

摘要

The transmission system (10) of the present invention is designed to transmit a plurality of signals between the transmitter and the receiver using a plurality of carriers and comprises a radio link characteristics estimator (4) configured to estimate the characteristics of a radio link between the transmitter and the receiver and a carrier quantity determination unit (3) configured to determine the number of carriers according to the result of the estimate by the radio link characteristics estimator (4). The radio link characteristics estimator (4) estimates the characteristics according to an interval in delay time of multipath signals and the number of the multipath signals. The carrier quantity determination unit (3) determines fewer carriers when multipath interference is small, and determines more carriers when the multipath interference is great.
