Random modulated processes and their use in binary modems with noise signals

The development of modern information society requires the development and implementation of new information-communication technologies, more productive systems of data processing and transmission. The variety of information sharing technologies – high-speed wired Ethernet, wireless mobile network technologies – requires the use of various terminal equipment and the application of new methods of signals analysis, synthesis and identification. Statistical research methods that are inseparably linked with ensuring of the accuracy, noise immunity and reliability of data transmission systems are promising in this regard. However, there is a number of unsolved problems of statistical studies that are common for information systems of various classes and purposes. This article is just devoted to the development of methods of analysis and synthesis of modems with noise modulated processes. As a result of the work of described devices a signal is received that has an additional peak of correlation function at the end of clock interval, the place and sign of which are information parameter, the estimation of which is made by demodulator. In the search of ways to improve noise immunity of noise signal the new schemes of ChSTU modems are patented and comparisons of noise immunity among themselves and with those of traditional systems are made
