Abstract

As M-ary orthogonal code spread-spectrum dispreading method is based on maximum correlation rule, a false dispreading result will be computed out in the situation of false alarm. Moreover, this false result will be handed down to the following units, which of course causes a waste of resources. In this essay, a dispreading method based on confidence analysis is proposed, and the simulation results show that the computed confidence degree traces the SER very well, providing the succeeding units a good reference.
