THE CHARACTERISTICS OF MODELS OF DATA TRANSMISSION CHANNELS

In this paper the main characteristics of communication channels are given. The relationship is shown between the maximum possible information rate and bandwidth in the communication channel. . The advantage is demonstrated of using a digital method of data processing in comparison with analog. The methods of data processing method direct sequence and frequency hopping methods. The territorial network at the regional levels are often used radio relay lines is justified. The advantages of point-to-point connections are shown.
