Abstract :
This report describes a synchronous pulse-type radio-telephone system for mobile communication use. The system features direct user-to-user communication without intermediate switching, a number of users have a common frequency band but avoid interference by operating in different time channels. Transmission takes place in bursts containing a large number of contiguous samples. This time-compression of the samples provides sufficient guard-time to accommodate the range of transmission delays in the specified area and other timing errors. A central clock is desirable but not indispensable. System calculations indicate 10 simultaneous simplex conversations per megacycle using delta modulation. The analysis assumes that subscribers are located in discrete areas. A large number of addresses, ringing and busy tones, command override, etc., are easily accommodated.
