  • Apparatus and method of decision-directed carrier recovery based on LMS method
    Patent number: 6735262
    Abstract: An apparatus and a method of decision-directed carrier recovery based on LMS method are provided. The apparatus of decision-directed carrier recovery based on LMS method includes frequency estimating device, phase estimating device, and complex number deciding device. The frequency estimating device compensates carrier frequency offset of external input signal and recovers carrier frequency of the input signal. The phase estimating device compensates phase offset of output signal resulted from the frequency estimating device and estimates carrier phase of the frequency estimated signal. The complex number deciding device determines a complex number for output signal resulted from the phase estimating device and provides the determined complex number to the frequency estimating device and the phase estimating device.
