Abstract
PURPOSE:To reduce greatly the throughput without lowering the signal detection capacity, by giving the logic decision to the level relation between the code of the Haar coefficient of the observation data row and the absolute value and thus delivering the waveform number having the higher possibility. CONSTITUTION:Observation data row S is supplied to Haar development circuit H, and then Haar coefficient ros S' is delivered from circuit H. Row S' is then supplied to correlation circuit A as well as to code decision circuit F and absolute value level decision circuit Z. Logic circuit R gives the decision to the level relation between the code of raw S' and the absolute value, and then supplies the decision output to selection switching circuit E. Circuit E selects the number of the waveform having the higher possibility among Haar coefficient rows N1-NN of the signals to be detected, and then supplies the number to circuit A. Circuit A carries out the multiplication of the outputs of circuits H and E to obtain the sum A'. Then sum A' is supplied to comparator P. Comparator P compares output A' of circuit A with set value T' of threshold level setting circuit T to deliver decision result O deciding whether the signal to be detected exists or not.
