I tried to use **PDU Head/Tail** to retrieve the tail without the ASM of a soft bit PDU stream:
```
BPSK Demodulator -> Sync and create PDU soft -> PDU Head/Tail -> ...
```
The sync block find…

The classes.txt file in the dataset is in the following order:
classes = ['32PSK',
'16APSK',
'32QAM',
'FM',
'GMSK',
'32APSK',
'OQPSK',
'8ASK',
'BPSK',
'8PSK',
'AM-SSB-SC',

I noticed that in src/Modules/Moden there is no code written apparently for anything other than BPSK and OOK. However the documentation claims to be able to do many other modulation formats in simula…

eg adapting https://github.com/radio-satellites/python-hrpt and it would use a recording of HRPT off IQEngine

Signals with narrow bandwidth like CW and also 1200 BPSK (Funcube) are harder to decode due to the doppler shift and the rather high change of center frequency in relation to the bandwidth.
So it i…

To support the frame sync block in BPSK, QPSK mode -- the timing recovery block tracks sample offset and decimates the input stream by sampling every Nth symbol. The timing is tracked using zero cross…

I met a problem,I don't ensure whether the order of list 'classes' is right in 'rml2018_01.py'.
Here the order.
`classes = ['32PSK',
'16APSK',
'32QAM',
'FM',
