Abstract

This paper investigates the legacy compatibility between IEEE 802.11n and 802.11a/g devices, focusing on the performance of legacy 802.11a/g auto-correlation and cross correlation joint time and frequency synchronization schemes operating over 802.11n networks. It is shown that synchronization schemes based on auto-correlation metric allow the backward compatibility, considering a different number of transmitting antennas operating over TGn channel models.
