Learn SDR: 16 Constellation Modulator

Learn SDR with Professor Jason Gallicchio at Harvey Mudd College
Lesson 16: Constellation Modulator
It does the Root Raised Cosine filtering
Packed versus Unpacked Bytes
HW: Look at QPSK and other built-in constellations. Don't bother trying to "decode" anything by hand -- this is very difficult before Timing and Carrier synchronization.
HW: Try fewer samples per symbol. 2 is the absolute minimum. Why does the bandwidth of the signal get bigger?

Hello Please help me to transfer a file with Constellation Modulator so that the files are the same at sender and receiver. Now I transferred them but the files changed. Thanks Maryam
