Hello, Thanks for your replies!
When I do that, the demodulator outputs unpacked bytes (0s and 1s). I tried using the “Pack K Bits” and “Unpacked to Packed” blocks separately (setting K = 8)
and it did not work. By “did not work” I mean, my input into the modulator were numbers between 0 and 15, and when I pack 8 bits at a time, I get numbers between 0 and 255. --------------------------------------- Matt Brandsema Assistant Research Professor Applied Research Laboratory at Penn State University Phone: c: (201) 259-3584 w: (814) 865-5783 From: Achilleas Anastasopoulos [mailto:address@hidden
...neither do you want the extended FEC encoder/decoder. Just send random symbols through the QAM modulator, add noise and demodulate with the QAM demodulator. Achilleas |
