| 摘要 |
The present invention relates to a method for detecting a pilot pattern, comprising a pilot signal sp(t), in a received signal r(t) implemented in an Orthogonal Frequency Division Multiplexing (OFDM) system. The method comprises the steps: computing a value of a log-likelihood function (τ0,&ngr;0) for a hypotheses space specified by the pilot signal sp(t) and an initial time frequency offset (τ0,&ngr;0), and relating the computed value to a reference value to detect the pilot pattern. |
