Filed: 1980-04-23
Abstract: PURPOSE:To suppress a code error noise without requiring an error detection code, by correcting only a receiving signal having a code error noise, and executing no additional processing to a receiving signal having no noise disturbance. CONSTITUTION:A receiving signal is bracketed to 1 block in the step 1, an amplitude value of the receiving is limited to a  prescribed value in the step 2, and in case it exceeds the threshold level for deciding the pause section of a signal in the step 3, it is suppressed so as to be within its threshold level, the time window is set in the step 4, and a linear forecasting coefficient of the receiving signal of 1 block portion is calculated in the step 5. In the step 6 to 9, being based on the linear forecasting coefficient, the forecasting value is calculated, and also being based on the information of a difference between the forecasting value and the actual signal value, the position where a code error noise is generated is decided exactly. In the step 10, in case a value of the code error noise which has been decided upon has exceeded the threshold level which has been set in advance, it proves to have a code error noise.
