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.
