STATISTICAL PROPERTIES OF THE DICON RECEIVER
Abstract
Statistical properties of the Dicon receiver are presented. The basic modulation-demodulation technique used in the Dicon system is frequencyshift keying and energy detection. That means an information bit is represented by a pulse of one of a pair of frequencies. This bit is detected by measuring the received energy in a band about each of the possible transmitted frequencies over an appropriate time interval and then determining which band contains the larger received energy. The energy measurement is made in the Dicon channel receiver. The final bit decision is performed by subtracting the outputs of two channel receivers tuned to the two information frequencies and determining the sign of the result. Results were obtained for a variety of parameters representative of the range of experimental conditions expected in West Ford communications. (Author)
