SYSTEM, APPARATUS, AND METHOD FOR A ROBUST SYNCHRONIZATION SCHEME FOR DIGITAL COMMUNICATION SYSTEMS

摘要

Synchronization sequence (preamble) known to the receiver a packet-based is formed as an integral part of a digital communication system. In this first operation of the digital communication system is the beginning of the effective detection signal (packet). The present invention provides for a method for detecting a preamble robust, system, apparatus and method. Method of the present invention has the following advantages: in which noise and interference robustness, which provides information that is necessary to position the FFT window for an OFDM- based modulation, which the real part of the peak that can be used for frame synchronization service, and finally it provides the peak for burst detection purposes. ; OFDM, receiver, the preamble, frame synchronization
