Abstract : The paper discusses the design and operation of a new digital signal detector that is characterized by the following operational features: (1) has low sensitivity to signal amplitude variations; (2) uses multiple signal bit measurements; (3) correlates these measurements in a network weighted to match operational conditions; and (4) determines the status of the detected signals by statistical methods. The new digital detector functions as a wave-form classifier; i.e., it samples sequential segments of the received signal waveform and encodes these data into binary digital words. These word groups are then applied to weighted networks that function as classifiers placing the sampled data into either the 'plus one' or 'minus one' categories. A detailed description of each of these functions is presented. (Author)
