ABSTRACT:
A frequency offset compensation estimation system and method for a wireless local area network. First, a preamble sequence of a frequency package is sent to a frequency offset estimation (FOE) device so that an initial frequency offset signal amount is obtained and sent to the frequency offset compensation (FOE) device for compensation. Then, the compensated signal is sent to a frequency offset residual phase estimation (FOS RPE) device so as to calculate an offset amount of the frequency and send it to the frequency offset residual phase compensation (FOS RPC) device for compensation. The present invention mainly employs a residual frequency offset estimation device (Residual FOE device) to estimate the residual frequency offset signal of each of the frequency signals compensated by the frequency compensation device and feedback it to the frequency compensation device for compensation. Therefore, the operation load of the frequency offset residual phase compensation (FOS RPC) device will be reduced so as to improve the operation efficiency of the system.
