<p>NEW FRAME AND TRAINING PATTERN STRUCTURE FOR MULTI-CARRIER SYSTEMS Abstract The present invention relates to a transmitting apparatus (54) for transmitting signals in a multi carrier system on the basis of a frame structure, each frame comprising at least two training patterns adjacent to each other in the frequency direction and at least two data patterns, said transmitting apparatus comprising pilot 5 mapping means (55) adapted to map the same sequence of pilot signals on frequency carriers of each of said at least two training patterns in a frame, each training pattern having the same length, data mapping means (58, 58', 58'") adapted to map data on frequency carriers of said at least two data patterns in a frame, transforming means (60) adapted to transform said training patterns and said data patterns from the frequency 10 domain into the time domain in order to generate a time domain transmission signal, and transmitting means (61) adapted to transmit said transmission signal. The present invention further relates to a corresponding transmitting method and a frame pattern for a multi carrier system. is (Fig. 16) Power-up tuning 39 position (example) 29"feuec t3me ,42 42 2 42 frequency time i 31 313 DtiiData Data 44 1Data Data 42 ii 43 Pelected by -- 45 46 Maximum data segment overlapping corridor Receiver tuning position Fig. 14 Super Frame | Super Frame Super Frome f- 47 47 47 Frame Frame - Frome 4849 50 51 52 48 f f JI53 GI signallin9I G DataG Data -52 48 Symbol symbol 1 symbol N Shortened training symbols: L1 signalling - Correlation - Phy layer and . -Syncronization channel partition Fig. 15 - Channel estimation information - frequency offset calculation</p> |
