Adaptive modulation system and method for tdma

摘要

A system and method for providing adjustable levels of information density in a communicated data stream in response to monitored communication link conditions is disclosed. In a preferred embodiment the data stream is a time division multiple access data stream providing data communication to a plurality of geographically separated systems. The information density of time bursts associated with each such system may be independently adjusted according to the disclosed invention based upon each such system's link conditions. A preferred embodiment of the invention utilizes a mapping technique in order to utilize a modulator adjusted for a high level information density to emulate lower level information density transmission.
