Abstract
Receiver for receiving a transmission signal comprising N frequency multiplexed data modulated carriers, having a good compromise between insensitivity to multipath reception and receiver complexity, and which may enable a reduction in transmission bandwidth and transmitter power. In such a receiver, modulation signals of the carriers are supplied by a frequency multiplex demodulator to a symbol detection device via an equalizer device. The equalizer device compensates distortion in the modulation signals supplied thereto, such that the symbol detection device may detect the transmitted data with reduced error probability. When the transmission signal reaches the receiver with different delay times, this distortion is mainly a kind of cross-talk between the modulation of adjacent carriers. Therefore substantial compensation is achieved by combining the modulation signal of a carder with signals representative of the data of the adjacent carriers. In the receiver, these signals may be obtained from the multiplex signal path between the frequency multiplex demodulator output and the output of the symbol detection device.
