Hi all:
Now I want to use the Trellis_encoder block in the GRC to make an example
for the convolutional code.In my opinion, I use Trellis_encoder to produce the
convolutional code, then make the convolutional code through the modulator and
demodulator(such as DPSK), finally use some block to decode the convolutional
code to get the original data.But after the data get out the demodulator,I do
not know how to decode it.
Here is the flow graph I used:
vector_source->throttle->Packed_to_Unpacked->Trellis_encoder->Packet_encoder->DPSK_mod->DPSK_demod->Packet_decoder->?
Can anyone tell me which block I should use after the Packet_decoder to
decode the convolutional code?
Thank you in advance.
