GFSK Mod

Hierarchical block for Gaussian Frequency Shift Key (GFSK) modulation.

The input is a byte stream (unsigned char) and the output is the complex modulated signal at baseband.

Parameters

Samples/Symbol

Samples per baud >= 2 (integer)

Sensitivity

Given to the Frequency Mod

BT

Gaussian filter bandwidth * symbol time (float)

Verbose

Print information about modulator?

Log

Print modulation data to files?

Unpack

Unpack input byte stream?

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.
