Abstract:
A method and apparatus of detecting a frame boundary by using a preamble are provided. The method includes delaying the preamble by a predetermined length of time, wherein the preamble includes an LTF and a code of the (n+1)th one of 2n sync sequences of the LTF is the inverse of a code of the last one of the sync sequences of STF; calculating a correlation value between the preamble and the delayed preamble; and detecting a frame boundary by comparing the correlation value with a threshold correlation value.
