Patent ID: 8274878

Claim:
A transmitting apparatus for transmitting signals in a multi carrier system on the basis of a frame structure, said transmitting apparatus comprising: a frame former configured to form frames of said frame structure, each frame comprising at least two preamble patterns adjacent to each other in the frequency direction and at least two data patterns following the at least two preamble patterns in the time direction in a time slot succeeding the time slot in which the at least two preamble patterns are located, wherein each of the at least two data patterns in a frame is respectively followed by further data patterns in succeeding time slots in the time direction, wherein all data patterns following each other in the time direction have a same frequency direction structure, each of the at least two preamble patterns, the at least two data patterns, and the further data patterns comprising a plurality of frequency carriers, wherein a length of each of the at least two preamble patterns is equal to or smaller than the effective receiving bandwidth of a receiving apparatus adapted for receiving said signals, 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 a same length, a data mapper configured to map data on frequency carriers of said at least two data patterns and said further data patterns in a frame, 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 to transmit said time domain transmission signal.
