WIPO Patent Application WO/2024/034409

Kind Code:

A1

Abstract:

Provided is a transmission device that is compatible with preexisting systems and can increase transfer efficiency. An orthogonal frequency division multiplexing transmission device comprising: a redundancy signal adding circuit that adds a redundancy signal of a prescribed number of sample points to a plurality of sample points of the output from an IFFT circuit or an IDFT circuit; and a sample point truncating circuit that discards a prescribed number of sample points from each of the front end and the rear end of the output from the redundancy signal adding circuit, wherein the transmission device is configured such that an output symbol of the sample point truncating circuit is transferred.
