Abstract: A transmitter for transmitting data signals to at least one communications device over a wired network on a plurality of carriers is provided, wherein the carriers are located in frequencies being allocated by one or more radio services, wherein each of the radio services is allocated to one or a plurality of frequency bands, the transmitter comprising a symbol generator configured to generate symbols based on the data signals; a processor configured to generate copies of the symbols and to determine an allocation of the copies onto the plurality of carriers, wherein a first copy and a second copy of each symbol are allocated to carriers located in frequency bands that are allocated to different radio services; and a modulator configured to modulate the copies of the symbols on the carriers in accordance with the determined allocation.

Abstract: A transmitting apparatus is provided for transmitting signals in a multi carrier system, in which pilot signals and data mapped on frequency carriers are transmitted in a transmission bandwidth, wherein a part of the transmission bandwidth is not used to transmit signals. The apparatus includes a pilot signal mapper for mapping pilot signals onto selected frequency carriers according to a pilot pattern that is adapted for a channel estimation in a corresponding receiving apparatus, the pilot pattern enabling a channel estimation for frequency carriers next to the part of the transmission bandwidth that is not used to transmit signals.
