In digital communication, the optimum detector for incoming binary sequence embedded in additive white Gaussian noise is the matched filter or correlation detector. This device is usually implemented by an integrate and dump circuit which requires the bit timing of the incoming sequence; this timing is supplied by the bit synchronizer.
This paper analyzes the steady state performance of an absolute value type of early-late-gate bit synchronizer, one of the suboptimum synchronizers, in terms of the steady state mean deviation of phase error (or magnitude of phase error's 1st moment), which is compared with experimental data. And the manner in which the performances of this system depend on loop parameter are also considered.
Suboptimum bit synchronizer 의 일종인 absolute value type of early-late-gate bit synchronizer 의 steady state performance 를 비교적 측정하기 쉬운 steady state mean deviation (평균편차) $E(\mid\lambda\mid)$ 로 분석, 이의 측정치와 비교했을 뿐아니라 loop parameter 가 $E(\mid\lambda\mid)$ 에 미치는 영향도 고려되었다.
