发明名称 METHOD AND CIRCUIT FOR FREQUENCY OFFSET ESTIMATION IN FREQUENCY DOMAIN IN THE ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING BASEBAND RECEIVER FOR IEEE 802.11A/G WIRELESS LAN STANDARD
摘要 A method for frequency offset estimation in frequency domain is provided. The method comprises the following steps. First, a phase angle of a signal field of the input signal after processed by Fast Fourier Transformation (FFT) and channel equalization is calculated. A frequency offset error originated from at least one frequency offset estimation process in time domain is then estimated according to the phase angle.
