METHOD AND DEVICE FOR PROCESSING A DIGITAL COMPLEX MODULATED SIGNAL WITHIN A POLAR MODULATION TRANSMISSION CHAIN

摘要

Method and device for processing a digital complex modulated signal within a polar modulation transmission chain Method of processing a digital complex modulated signal, comprising performing pre-processing said digital complex modulated signal (DCMS) for obtaining a pre-processed digital complex modulated signal (PPRS) and performing a Cartesian to polar conversion of said pre-processed signal, said pre-processing (11) including analysing the trajectory of said digital complex modulated signal and if said trajectory crosses a region (RAO) around the origin (O) of the complex plane, modifying (112) said digital complex modulated signal such that said pre-processed signal has a modified trajectory avoiding said region.
