Abstract

Signal detectors often utilize nonlinear statistics of observations rather than the observation as they are. The sign statistic, a typical example of the nonlinear statistics, for example, relies oかy on the sign information of observations. In this letter, a qualitative analysis is presented that the correlation coefficients between the statistics and original observations can be used to predict the asymptotic performance of a detection schemes utilizing the nonlinear statistics.

많은 경우에 신호 검파기들은 관측량 그 자체보다는 관측량의 비선형 통계량을 쓴다. 부호 통계량은 이러한 비선형 통계량의 대표적 보기인데 관측량의 부호정보만을 가지고 있다. 이 논문에서는 관측량과 부호 통계량, 크기 통계량과 같은 비선형 통계량들 사이의 상관 계수를 얻어내고, 비선형 통계량들을 쓰는 검파기들의 점근적 성능을 분석한다.
