Abstract:

The criterion of minimum average loss of information is applied to an information transfer system. A wideband system for transferring information in binary code is considered and it is assumed that the probability of transmission of each of two possible meanings of a signal is predetermined. A system is dealt with which utilizes a threshold device and whose self-tuning process consists of the following operations 1 accumulation of information regarding noise and the state of the system 2 computation of the efficiency factor 3 determination of the direction and magnitude of the shift in threshold level and 4 establishment of the new threshold value. An algorithm for the operation of the receiver section is presented in a logic form which has been verified on an analog computer under conditions of additive noise of unknown statistical nature.
