Abstract
A transceiver system and method comprises a transmitter and a receiver. The transmitter includes a synthesis filter bank and an overlapping unit. The synthesis filter bank generates and modulates a set of wavelets. The overlapping unit generates a multicarrier signal carrying the information data and provides it to the communication line. The receiver includes a separating unit having a separating shift register and an analyzing filter bank having an N-points FFT unit and a demodulator coupled thereto. The method includes at the transmitter end providing a sequence of prototype wavelets by using N-points IFFT, modulating the sequence of the prototype wavelets by said information data, overlapping the modulated prototype wavelets to generate a multicarrier signal carrying the information data. The method includes at the receiver end separating overlapped wavelets from the multicarrier signal, analyzing the separated wavelets by using an N-points FFT, and demodulating spectral frequency amplitudes of the wavelets.
