GMSK Modulator

GMSK modulator block.

Parameters

Samples/Symbol

Samples per symbol.

3 dB Time-Bandwith Product

For LSRC, this is the rolloff factor. For Gaussian pulses, this is the 3 dB time-bandwidth product.

Pulse Duration (Symbols)

The length of the phase duration in symbols. For L=1, this yields full- response CPM symbols, for L > 1, partial-response.

Example Flowgraph

This is an example flowgraph modified from https://github.com/gnuradio/gnuradio/blob/main/gr-channels/examples/demo_gmsk.grc to use a GMSK Demod block
