METHOD OF TIMING RECOVERY AND TRACKING USING CORRELATION VALUE ESTIMATION WINDOW AND COMPUTER-READABLE MEDIUM HAVING THEREON PROGRAM PERFORMING FUNCTION EMBODYING THE SAME

摘要

A method for recovering and tracking a timing using a correlation value estimation window and a computer-readable medium having the program performing the functions embodying the same are provided to accurately recover and track the timing by changing the correlation value estimation window or a threshold value according to channel characteristics. An upper position and a lower position of a correlation value estimation window are limited to include a symbol position with a large correlation value based on a window of a preamble field(S110). The correlation value is checked after an upper limit of the correlation value estimation window reaches on a window corresponding to the preamble field, an FSW(Frame Start Word) field, or a CSW(Channel Start Word) field. It is determined whether the correlation value extends a threshold value(S120). When the correlation value is greater than the threshold value, the upper and lower limits of the correlation value estimation window are updated, and the next window is calculated(S130).
