Energy change detection of appearance of the primary signal with unknown power

초록

In this paper, a sequential change detection scheme is proposed to detect the emergence of a primary signal with unknown power. It can be shown that the proposed test can do better than the generalized likelihood ratio (GLR) test, under the same worst case average run length (ARL) of detection delay constraint. And performance of our test is evaluated using theoretical analysis and numerical simulations. ©2009 IEEE.
