<p>A multi-carrier transmitter and receiver for performing data transmission. The multicarrier transmitter and receiver comprise a first inverse fast Fourier transformer for performing an Inverse Fast Fourier Transform (IFFT) on a parallel input data signal, an imaginary component filter for filtering out the imaginary component of an output signal of the first inverse fast Fourier transformer and a real component filter for filtering out the real component of the output signal of the, first inverse fast Fourier transformer. The multicarrier transmitter and receiver also comprise a first prototype filter comprising a polyphase filter having real coefficients. The first prototype filter accepts output data from the imaginary component filter. The multicarrier transmitter and receiver also comprise a second prototype filter comprising a polyphase filter having real coefficients which are selected by taking the real coefficients of the first prototype filter and inverting the sign of each odd-numbered real coefficient. The second prototype filter accepts output data from said real component filter. A combined OFDM and Wavelet multi-carrier transceiver is proposed sharing an IFFT block.</p> |
