FIELD: radio engineering, communication.
SUBSTANCE: invention relates to a transmitting apparatus (54) for transmitting signals in a multi-carrier system based on a frame structure, each frame comprising at least two training structures adjacent to each other in the frequency direction and at least two data structures, said transmitting apparatus comprising: pilot mapping means (55) adapted to map the same sequence of pilot signals on frequency carriers of each of said at least two training structures in a frame, each training structure having the same length, data mapping means (58, 58', 58") adapted to map data on frequency carriers of said at least two data structures in a frame, transforming means (60) adapted to transform said training structures and said data structures from the frequency domain into the time domain in order to generate a time domain transmission signal, and transmitting means (61) adapted to transmit said transmission signal.
EFFECT: providing flexibility of turning to any required part of the transmission band.
