Abstract:
Disclosed is a CFO estimation method comprising: generating a first function defined by reception signals in two successive OFDM symbols for a particular subcarrier; generating a second function defined on the basis of a sign of a real part of the first function; repeatedly performing a process of generating the first function and the second function for an entire subcarrier set; and determining a phase of a third function obtained by adding results of the repeated performance to be a residual CFO.
