THEORETICAL INVESTIGATION OF DUAL RATE TRANSMISSIONS OVER GAUSSIAN MULTIPLICATIVE CIRCUITS
Abstract
The simplest form of a variable data rate communication system, an on-off system, which in the ideal case has been shown to be almost as good as the continuously variable rate system is detailed. The effe ts of Rayleigh fading and additive Gaussian noise in both the forward and feedback channels are studied. The imperfect feedback channel introduces the possibility that the receiver may not know when data is being transmitted, thus causing a so-called message displacement in which a block of data is missed or a block of noise is inserted in the received message. An on-off, binary comm nication system is developed which can be designed to have a very low probability of message displacement together with data rates which are close to optimum. (Author)
