Patent ID: 8218614

Claim:
An electronic equalization and electronic depolarization method, comprising: converting a received time domain signal into a frequency domain signal; detecting a Synchronization Sequence (SS) in the received time domain signal, and obtaining a corresponding control signal, comprising: intercepting the received time domain signal through a moving window; evaluating a cross-correlation between the intercepted time domain signal and the SS, and obtaining a cross-correlation value; and comparing the cross-correlation value with a preset threshold, outputting a control signal indicating that the received time domain signal is the SS if the cross-correlation value is greater than the preset threshold, and outputting a control signal indicating that the received time domain signal is not the SS if the cross-correlation value is smaller than the preset threshold; calculating parameters required by electronic equalization and electronic depolarization by a least-square algorithm when the control signal indicates that the received time domain signal is the SS; and performing the electronic equalization and the electronic depolarization on the frequency domain signal by utilizing the parameters.
