Title:
METHODS OF PROVIDING SIGNAL PARAMETER INFORMATION USING DELTA-MODULATION AND RELATED SYSTEMS AND TERMINALS
Document Type and Number:
WIPO Patent Application WO2002027949
Kind Code:
A3
Abstract:
Signal parameter information can be transmitted from a first communications device to a second communications device. For example, communications can be received at the first communications device from the second communications device, and a plurality of samples of a signal parameter can be generated characterizing the received communications. In addition, a plurality of delta-modulation values can be calculated responsive to the respective samples of the signal parameter wherein the plurality of delta-modulation values are associated with corresponding ones of the plurality of samples of the signal parameter characterizing the received communications. The delta-modulation values can be transmitted to the second communications device. Related devices are also discussed.
