Abstract
The present invention relates to signal transmitting/receiving apparatuses. The signal transmitting apparatus includes an inverse discrete Fourier transform module, a cyclic prefix adding module, a preamble adding module, and a digital-analog converting module. The inverse discrete Fourier transform module receives modulated data, performs inverse discrete Fourier transform, and generates a first symbol. The cyclic prefix adding module adds a predetermined cyclic prefix to the first symbol, and generates a second symbol. The preamble adding module adds a predetermined preamble to the second symbol, and generates a third symbol. The digital-analog converting module converts the third symbol including the cyclic prefix and the preamble into an analog symbol.
