Hi list,

I’m a bit confused about the constellation blocks that are going to replace
the deprecated specific modulation blocks.
In previous examples, we used

[Signal]->[Packet Encoder]->[Mod Block]->[Channel]->[Demod Block]->[Packet
Decoder]->[Sink].

Now, I’ve tried to replace this chain with non-deprecated blocks. First,
I’m wondering why I can choose differential encoding in the „Constellation
Object“ block as well as in the „Constellation Modulator“ block. What
happens if I only select it in one of them? Also, there is no way to select
differential encoding in the „Constellation Decoder“, but AFAIK the
receiver must know if differential encoding is used. How is this correctly
intended?
Second, I’m wondering what is going to replace the deprecated „Packet
Encoder“. Theoretically, we need an encoding to transfer the infinite input
alphabet (float) to a finite output alphabet (int8). I’ve not found a block
that handles this task. Any ideas on how to replace the signal chain above
is appreciated!

Best,
Sebastian
