RECEPTEUR FBMC A COMPENSATION D'OFFSET DE FREQUENCE PORTEUSE |
摘要 |
<p>The invention concerns a filter bank receiver (FBMC) effecting a carrier frequency offset compensation in the frequency domain. The receiver comprises an FFT module extended by the overlap factor (610), a module (630) offsetting a predetermined number of subcarriers at the output of the FFT followed by a filter for reducing interference between subcarriers (640), the number of subcarriers and the coefficients of the interference reduction filter being determined from an estimation () of the frequency offset. The vector of samples thus obtained is then the subject of channel equalisation (650) before being filtered by a battery of analysis filters and spectrally de-spread (660). Finally, after spectral de-spreading, the vector of samples is demodulated by an OQAM demodulation (670) so as to recover the transmitted data.</p> |
