APPARATUS AND METHOD FOR DETECTING PREAMBLE AND RF REPEATING SYSTEM USING THE SAME
摘要
<p>A preamble detecting apparatus includes: a time delayer for delaying a TDD frame signal (S(t)) by a preamble period (preferably, a TDD frame length); a complex correlator for calculating a complex correlation between the time-delayed signal (S(t-TF)) and the TDD frame signal (S(t)); and a preamble position detector for detecting a preamble position using an output value (complex correlation value (C(t))) of the complex correlator.</p>
