A METHOD AND APPARATUS FOR LOCALLY DETECTING SIGNAL, A METHOD AND APPARATUS FOR DETECTING SIGNAL AT CENTER, AND A SYSTEM FOR DETECTING SIGNAL

摘要

A method and apparatus for locally detecting signal, a method and apparatus for detecting signal at center, and a system for detecting signal are disclosed. The method for locally detecting signal comprises: according to the determined quantification threshold corresponding to the local node, detection statistic corresponding to the signal to be detected is quantified and the quantification result is obtained. The quantification result is used for judging whether the signal to be detected is valid signal. The method for detecting signal at center comprises: obtaining the quantification result which is acquired through quantifying detection statistic by local node. According to the quantification result, global decision result indicating whether the signal to be detected is valid signal is obtained. Applying the solutions above, detection performance can be expediently and simply improved.
