Profiling method of channel profiler and input signal

摘要

This invention regards method and the channel profiler which the input signal profile are done. With such method, the preamble of the input signal is identified, the reference waveform which is suitable to the preamble which next, is identified is extracted. After that, cross correlation with the ripple mark and the input signal which are extracted is proven. Because of that, the channel profiler has automatic Cori later the preamble of the input signal is identified. In addition as for the channel profiler it has with cross Cori later cross correlation with the opposite discrete Fourier transform module which remembers the reference waveform and the reference waveform which is suitable to the preamble and the said preamble is proven.
