Abstract
On the TDD system, the uplink and downlink transmission share the same frequency but are seperated in time. In this paper we just consider the uplink transmission. The BWA system in this paper should be accepted the adaptive modulation. Each uplink burst shall begin with an uplink preamble. The reception of an uplink burst is the most challenging from a synchronization perspective. The burst detection, power estimation, symbol synchronization and carrier synchronization should be obtained from the preamble. It will be shown in this paper, how can get a burst detection by preambles and extract the synchronization parameter from preamble.
