摘要

A description is presented of the method of dynamic carrier control (DCC), which is characterized by a high margin of safety against adjacent-channel and common-channel interferences, together with remarkable savings in consumption. The special characteristics of this method are presented, along with the technical solutions for PSM and class B modulated transmitters. Examples of recent modifications of older transmitters to DCC are described as well. Experience gathered during various tests on a test platform and at different users' sites is reported.
