In radio technology, Differential Phasor refers to differential decoding based on phase change. It uses the phase difference between two symbols to determine the output symbol1. This technique can be used in various applications such as demodulating multilevel differential phase-shift keyed (DxPSK) signals2.
out[i] = in[i] * conj(in[i-1])
Parameters
None
Example Flowgraph
Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
