摘要：
A symbol boundary detection device and a method thereof for use in a receiver of a multi-channel communication system. The device utilizes a threshold to make an auxiliary judgement so as to select a proper symbol boundary reference point within an early range. The threshold may be flexibly set in response to different characteristics of the systems. In addition, a pilot symbol guard interval matched filter is further utilized to determine whether a pilot symbol guard interval is received.
