Channel estimation and symbol boundary detection method

摘要

A channel estimation method for receiving a received signal by a receiver is disclosed. The received signal comprises a plurality of data bursts which are transmitted to the receiver via a plurality of path channels, wherein each of the data bursts comprises a plurality of preamble symbols. The channel estimation method includes the following steps: firstly, at least one correlation pattern is generated according to the decoded preamble symbols. Then, a cross correlation of the correlation pattern with the received signal is performed to yield at least one correlation result of channel impulse response (CIR). Wherein, the symbol boundary of the received signal is decided according to the correlation result.
