The article considers the problem of processing of signals and creation of error-correcting connection. Resistance to various types of distortions, increased performance and increased noise immunity are the important tasks that the developers of equipment for receiving and processing signals. In the text the block diagram and the principle of the proposed algorithm in digital coherent demodulation of signals quadrature amplitude manipulation, outlines its advantages and disadvantages relative to other known algorithms. Produced statistical simulation of the device that will work on the basis of the proposed algorithm in digital coherent demodulation of signals quadrature amplitude manipulation. To create an error-correcting connection, it is possible to use the developed algorithms and the corresponding device coherent digital demodulation of signals quadrature amplitude manipulation. The simulation is the estimation of noise immunity of coherent demodulation of signals quadrature amplitude manipulation.
