ABSTRACT:
A phase error correction technique in data communication receivers such as WLAN (Wireless Local Area Network) receivers is provided. A signal having a phase error is received, and a phase error correction mechanism having a loop structure is operated on the input signal to correct the phase error. The corrected signal still has a residual phase error. The residual phase error is then compensated taking into account a loop time delay of the loop structure. Further, a phase change rate may be taken into account, and a smoothing process may additionally be performed.
