<p>The invention relates to methods and systems of transmitting and receiving data in multicarrier modulation systems, in which representations of input data are modulated on groups of subcarriers, and predetermined amounts of intersymbol interference are introduced between symbols. In the transmitter, adjacent subcarriers are respectively modulated with a positive and negative representation of an input data, and adjacent symbols are overlapped by half a symbol period. In the receiver, representations of the transmitted data are demodulated from the subcarriers, and the intersymbol interference removed so that the input data can be estimated. This provides particular advantages over conventional OFDM systems, while ensuring relatively high bandwidth efficiency.</p> |
