Effectiveness of message transmission with the aid of analog coding

V. N. Bronnikov, V. I. Poddubnyak

Abstract


The paper considers a method of message transmission based on taking the sum of real number modules instead of 0 and 1 when defining the checking and coding symbols in the algorithms of coding and decoding. The checking relationships are used as separate duplicating channels of sample transmission with subsequent pooling of the sample estimates obtained into the sum, which is weighted by the least squares method. It is shown that the use of the method suggested makes it possible to raise noise immunity substantially in comparison to the known methods.
