| titleOfInvention | Signal reconstruction method based on rotation matrix error estimation for alternative sampling system |
| abstract | The invention discloses a signal reconstruction method based on rotation matrix error estimation for an alternative sampling system. The method comprises the following steps: I, initial parameter setting; II, training sample construction: transforming sample sequences of M A/D (Analog to Digital) conversion chips in the same time interval t to a frequency domain by means of fast Fourier transform to obtain M training samples, wherein the M training samples construct a training sample set; III, time base error estimation: selection of dual frequency points for error estimation, covariance matrix estimation, feature decomposition, extraction of a large feature value and a corresponding feature vector thereof and time base error estimation; IV, gain error estimation; V, gain error compensation; VI, weight vector reconstruction; VII, signal reconstruction in a frequency domain; VIII, inverse fast Fourier transform. The method disclosed by the invention is simple in steps, reasonable in design, convenient to implement and good in application effect, and the problems of complex error estimating process, large calculation amount, large signal error after reconstruction and the like existing in the conventional signal reconstruction method for a parallel alternative sampling system can be solved effectively. |
