A digital signal transmitter in which multiple data streams are each transmitted by modulation of a respective frequency band within one of a group of frequency channels, the frequency bands each occupying no more than a predetermined maximum bandwidth less than or equal to the channel width; comprises means for transmitting at respective frequency positions within each frequency channel, one or more instances of band information defining the frequency bands corresponding to all of the data streams carried within that frequency channel, the one or more instances being arranged so that any portion of the frequency channel equal in extent to the predetermined maximum bandwidth includes at least one instance of the band information.

Digital signal transmission and reception

A transmitting apparatus for transmitting signals in a multi carrier system on the basis of a frame structure, each frame comprising at least two preamble patterns adjacent to each other in the frequency direction and at least two data patterns, said transmitting apparatus comprising a pilot mapper configured to map the same sequence of pilot signals on frequency carriers of each of said at least two preamble patterns in a frame, each preamble pattern having the same length, a data mapper configured to map data on frequency carriers of said at least two data patterns in a frame a transformer configured to transform said preamble patterns and said data patterns from the frequency domain into the time domain in order to generate a time domain transmission signal, and a transmitter configured transmit said transmission signal.
