Frank,
I just commited an update on fsm_utils.py where I added two
helper functions:
fsm_concatenate(f1,f2)
that concatenates two FSMs into one (this is what you need in your project)
and
fsm_radix(f,n) which generates the equivalent FSM resulting from
operating the original FSM for n steps.
Ach
Frank,
this is a nice example of combining 2 FSMs to create a
bigger one that describes the overall system:
The DQPSK can be described as an FSM with inputs x and outputs y.
Both x,y are integers (not complex numbers).
Then the ISI channel can be thought of as another FSM with input
y and output
Hello,
I am new at dsp and I hope that I do not bother you which a
stupid question:
I want to use the gr_trellis block as an ISI equalizier for a
burst type (pi/4)-DQPSK system. Therefore I have two questions:
1) I think that I know how I have to expand the fsm_utils.
make_isi_lookup() function
