demodulate

To isolate a data signal from a carrier wave. The demodulation circuit uses the unmodulated carrier as a reference signal and compares it to the received signal. See modulation and carrier.

Other methods to demodulation also shed low error rates, such as the AG-Zernike algorithm, but, using these two methods for example, the algorithm becomes very complex, since it is necessary to perform a lot of computational processes such as data mutations, data changes from binary to real, and a lot of variables to be estimated (a minimum of 7 variables).
