摘要

Apparatus signal generator OFDM (10c) to generate OFDM transmission signals Absolute (s (t)) partirde OFDM symbols, each comprising a plurality of OFDM subcarriers for transmission in UN5 transmission system multicarrier data said apparatus comprising: - one multiplication unit (31) for multiplying the OFDM symbols by a factor of paracompensar multiplication common phase rotations of the OFDM subcarriers of said OFDM symbol podríanintroducirse by mixing said complex time-domain samples of the symbol OFDMelevándolas from a frequency baseband to a frequency passband by lautilización a mixing frequency (fc), - a means of transformed inverse DFT (13) to transform, by a Fourier transform discretainversa, an OFDM symbol into complex time-domain samples and - a means of frequency mixing (16) for mixing said complex samples s Time Domain dichosímbolo OFDM so that they rise from a baseband frequency to a frequency depaso band using said mixing frequency (fc) in order to obtain said signal transmisiónde Absolute OFDM (s ( t)).
