Summary:A method for high-speed synchronization comprises the following steps of: calculating first correlation values corresponding to each of input samples based on the input samples and a code sequence generated from a received signal and corresponding to a first symbol interval; calculating phase differences corresponding to each of the input samples based on the first correlation values and second correlation values corresponding to a second symbol interval preceding the first symbol interval; updating cumulative phase differences corresponding to each of the input samples based on the phase differences; and detecting a symbol boundary based on the updated cumulative phase differences. 고속 동기화를 위한 방법은, 수신 신호로부터 생성되고 제1 심볼 구간에 대응하는 입력 샘플들 및 코드 시퀀스에 기초하여, 입력 샘플들 각각에 대응하는 제1 상관값들을 계산하는 단계, 제1 상관값들 및 제1 심볼 구간에 선행하는 제2 심볼 구간에 대응하는 제2 상관값들에 기초하여, 입력 샘플들 각각에 대응하는 위상차들을 계산하는 단계, 위상차들에 기초하여, 입력 샘플들 각각에 대응하는 누적 위상차들을 갱신하는 단계, 및 갱신된 누적 위상차들에 기초하여, 심볼 경계를 검출하는 단계를 포함할 수 있다.
