| 摘要 |
The present invention is directed to a transmitter (200) and receiver (400, 500) for filterbank multicarrier (FBMC) communication. The transmitter (200) comprises a processor (201) adapted to calculate two auxiliary pilot symbols, and a precoder (202) adapted to insert the two calculated auxiliary pilot symbols A7 and A8 into a symbol structure (300) of symbols, the symbols adjacently surrounding a main pilot symbol P, wherein the precoder (202) is adapted to insert the two auxiliary pilot symbols A7 and A8 at two symbol positions of the symbol structure (300), which are symmetric to the main pilot symbol P in a time domain and/or in a frequency domain. The receiver( 400, 500) comprises an analyzer (401) adapted to extract from at least one FBMC data packet received via a transmission channel the main pilot symbol P and the two auxiliary pilot symbols A7 and A8 included in the symbol structure (300) of symbols, the symbols adjacently surrounding the main pilot symbol, and a channel estimator (402) adapted to estimate a channel response of the transmission channel based on the main pilot symbol P and based on the two auxiliary pilot symbols A7 and A8. |
