METHOD FOR SELF TIMING DETECTION OF FRAME SYNCHRONIZATION

A self-timing detection method for frame synchronization is disclosed. The self-timing detection method may include a step of performing frame synchronization using a preamble constituted with four code sequences, wherein the phase of one code sequence included in the preamble is reverse of those of the other code sequences. The step of performing the frame synchronization includes the steps of: computing a first output that is a correlation coefficient of two input signals by using a zero-padded signal produced from the code sequence via an interpolator and a received pulse as the two input signals; putting the last peak value among four peak values corresponding to the first output as a second output; and finding self-timing in a bit range corresponding to the second output.
