Abstract : The author examined and analyzed methods used in contemporary technology of radio communication for transmission of information which are able to counteract the types of distortion mentioned and provide more complete utilization of potential carrying capacity of communication channels. The book consists of twelve chapters which cover the following topics: (1) Evaluation of methods of signal transmission from the standpoint of utilizing maximal carrying capacity of a communication channel; (2) A brief characterization of interference affecting a receiver; (3) Radiotelegraph communications without fadeout in the process of propagation; (4) Radiotelegraph communications with fadeout of received signals; (5) Radiotelegraph communications with multipath effect; (6) Theoretical considerations of ideal systems of telegraph signal transmission; (7) Radio communication systems using wideband signals with spectrum of white noise type; (8) Data transmission over radio communication channels; (9) Use of optimal coding as a means of matching the method of binary signal transmission with peculiarities of radio wave propagation; (10) Radio telephone communications in the absence of fadeout; (11) Radio telephone communications with allowance for fadeout; and (12) Telephony by means of wideband systems.
