Paper Abstract

This paper presents some new methods to estimate the start of the frame and coarse frequency offset jointly based on standardized 10 short training symbols in 802.11a. Through simulations, it is shown that the metric functions of the frame synchronization can form sharp peak to avoid the ambiguity introduced by multipath effects at low SNR. So it performs more accurately in the frame synchronization. It also jointly realizes coarse frequency offet estimation with wide estimation range.
