Abstract :
It is shown analytical and simulation results on 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 an auto-correlation synchronization scheme allows the legacy compatibility over AWGN and fading channels.
