A high accurate electronic instrument transformer calibration system is introduced in this paper. The system uses the fourth-order convolution window algorithm for the error calculation method. Compared with Fast Fourier Transform, which is recommended by standard IEC-60044-8 (Electronic current transformers), it has higher accuracy. The relative measuring(More)
In recent years, the MUSIC timing estimator were proposed for direct-sequence code-division multiple access (DS-CDMA) signals. It has been generally assumed that the channel noise is temporally white. However it may be invalid in practice due to, for instance, the presence of some narrowband interference or the lumping of secondary users into with the(More)
