[Ground-station] Now that we've heard some good news... LDPC block work needed - LDPC team alert

[Ahmet Inan]

Yeah, I did the math last night to get soft information from BPSK,
QPSK and 8PSK modulation and it would be nice if someone could look
over it.
I am not entirely sure if I got the SNR stuff right but it works very well.

Also, please beware that my 8PSK is Pi/8 rotated.

I put the new PSK stuff into the psk branch in order not to disturb
the others using the master tree:
