Abstract
Official abstract text for this publication.
A system and method for data communication over a cellular communications network that allows the transmission of digital data over a voice channel using a vocoder that monitors parameters of a Levinson Durbin recursion and then uses full rate CELP if the monitored prediction error falls to below a predetermined threshold within a pre-selected number of iterations of the recursion. The system and method encode digital data to be transmitted using a continuous signal modulation technique at a selected bit rate and one or more frequencies that are selected such that the resulting modulated carrier signal is processed by the vocoder using full rate CELP as a result of the monitored prediction error.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of sending data between a vehicle and central facility over a wireless communication system, comprising the steps of: encoding data sent in either direction between the vehicle and central facility using continuous signal modulation of a carrier signal such that the modulated carrier signal contains no more than four significant frequency components; transferring the modulated carrier signal between the vehicle and central facility using a n…
