4.Because the CORDIC algorithm can change the arctan function and round of angle to addition and shift operation, the novel model presented in the paper can complete frequency offset estimation and correction in digital field in the same time.
5.(2)When the intensity of white background light on the cornea attains 4.07μw/cm~2,the peak of the spectral sensitivity curve of the round scad is displaced some30 nm toward the long wavelength,i. e. at 520 nm(Purkinje shift).
