ADAPTIVE ALGORITHM OF SIGNAL PROCESSING
Nowadays adaptive systems are used in such realms of science and technology as communication, radiolocation, sonar localisation, seismology, navigation, medicine, etc. The specific features of adaptive algorithms firstly include the ability to adapt to circumstances in order to fulfill the stated problem. These features allow expanding the application of the algorithms in different types of digital signal processing. The aim usually posed for an adaptive device is raising the ratio of signal power to interference power at the output as compared with the corresponding ratio at the input. In this case the algorithm solving the problem is considered; it provides reproduction of a non-distorted signal form unlike matched filters. As a rule matched filtering is accompanied with signal form distortion because an output signal of a matched filter repeats the autocorrelation function of an input signal.
