| titleOfInvention | The method and device that a kind of time-frequency combination channel based on compressed sensing is estimated |
| abstract | The invention discloses the method and device that a kind of time-frequency combination channel based on compressed sensing is estimated.The method comprising the steps of: S1. carries out the first estimation of the channel impulse response of current demand signal frame, it is thus achieved that the rough estimate information of channel impulse response；S2. according to the rough estimate information of channel impulse response, the loop restructuring of the OFDM data block of current demand signal frame is carried out, it is thus achieved that the OFDM data block of reconstruct；The rough estimate information of the channel impulse response S3. obtained according to step S1, the pilot frequency information in the OFDM data block of reconstruct is utilized to be compressed perception, obtaining the accurate estimated information of channel impulse response, described accurate estimated information is as the estimated result of the channel impulse response of current demand signal frame.The method of the present invention can improve block transmission system opposing maximum multipath time delay length, precision of channel estimation and system spectrum utilization rate, still has good channel estimating performance in the case of maximum multipath time delay exceedes protection interval. |
