Abstract:
1. A filter bank based multicarrier signal transmission system, comprising: at least an emitter that comprises an iFFT block adapted to provide at an output thereof the inverse Fourier transform of an input signal of the emitter, a set of first memories, and a first weighted summation device; a plurality of switches each having an input connected to the output of said iFFT block, an input connected to one of said first memories and an output connected to another of said first memories; at least one receiver that comprises a FFT block adapted to provide at an output thereof the Fourier transform of the input signal of the receiver, a set of second memories, a second weighted summation device, and other switches each having an input connected to the input of said receiver, an input connected to one of said second memories and an output connected to another of said second memories; and modulation means of the signal using the Offset Quadrature Amplitude Modulation (OQAM) method, wherein the emitter and receiver each comprise two polyphase networks equipped with preloading means of the corresponding first memories and second memories.
