摘要： A multi-carrier receiver which dispenses with a guard interval and avoids an influence of an intersymbol interference (ISI) based on the height of the guard interval. This multi-carrier receiver has a serial/parallel converter for receiving a multi-carrier signal to convert it into a parallel signal, a Fourier transformer for selecting a multi-carrier signal over a section longer than one symbol of the received multi-carrier signal from an output of the serial/parallel converter to subject the selected multi-carrier signal to discrete Fourier transform, a channel compensator for subjecting the Fourier transform signal to channel equalization, a matrix conveter for contracting the dimension of the signal of channel equalized signal down to the dimension of the received multi-carrier signal, a parallel/serial converter for converting the output of the matrix converter into a serial signal, and a demodulator for matching the output of the parallel/serial converter with the modulator on a transmitter side, and a decoder for matching it with an encoder.

摘要： A transmission method (1) for an N carrier transmitter (EM). The principle of the method is to select a set of carriers from the N carriers and distribute them amongst subgroups in application of a determined criterion and to determine a set of powers transmitted per subgroup that complies with an optimum frequency distribution of the total power transmitted by said set among the subcarriers of the set, by minimizing an overall error criterion (BER) under the constraint that the sum of the powers of a set is equal to the product of the number Ntg of carriers of the subgroup multiplied by the total mean power transmitted over the N carriers.

摘要： The present invention relates to a transmission method for a transmitter having Nt transmit antennas. The method (1) spreads symbols in two dimensions by means of a spreading code, the symbols coming from a signal for transmission over Nfft sub-carriers via the Nt transmit antennas.
