 * The result is a stream of symbols without phase-/frequency-/timing-offset, which includes the current modulation as stream tags
 
 ## Usage
-There is a flowgraph in examples/ which demonstrates the classification receiver chain.

 ## Current Constraints
 * Just setting stream tags, no actual demodulation of the signal
 * If there is only noise, always 8PSK will be classified
-* We need to know the used pulse form
