Abstract

It is investigated the performance of legacy IEEE 802.11a time synchronization algorithms when the synchronization preamble is transmitted by IEEE 802.11n devices with multiple transmitting antennas using cyclic shift diversity. It is concluded that the backward compatibility is achieved when the time synchronization is implemented using an auto-correlation maximum normalization metric.
