Instead of a UChar to Float block, you want to use a Chunks to Symbols
block (with 1, 3, -1, -3 in the Symbol Table and Dimension = 1).

Dear Marcus,
Thanks for your response. First of all, it is been a while
for answering your response and I am sorry about that. I could not try
your solution until these days. Unfortunately, I still couldn't get
over my problem on M-FSK modulation. When I try your solution, "bits
to symbols and after that using frequency modulator", I managed to
convert bits to integers using the packed to unpacked block. However,
after subtracting data from 1.5(for M=4), that point I am stuck. Using
frequency modulator will make an FSK modulated signal?
If you can still help, I will be appreciated. Thanks in advance.
Yours sincerely.

Really quickly, I need to get going:
with unpacked-to-packed (or vice versa) you can convert your bit
stream
to integers between 0 and 3. Convert to float, subtract 1.5, use with
frequency modulator?
Best regards,
Marcus
