In our project, we need to compare the constellation points of a 16 QAM modulation system between the transmission end (at the AWG end) and the receiver end (at our OMA system).How the AWG IQ tools (M8195A 2Ch 64GSa/s 256 memory) encodes/converts the input data stream (binary) into the I and Q signals? Is there any manual to have a better understanding on this algorithm?
