given the input binary sequence 010100110101000111 sketch the waveforms of the inphase and quadrature components of a modulated wave obtained by using 8-ary QAM signal set and sketch the 8ary QAM wave form iteself for the input binary sequence specified in the pervious part
if it is 8QAM then you have 8 points in your constellation, which means you can send 3 bits at a time (i.e. 2³=8)
Group the binary sequence 3-by-3: 010-100-110-101-000-111
which is equivalent to: 2-4-6-5-0-7. Thus you need to send the QAM signals, which corresponds to these numbers, consequently from the transmitter.
Thats what I know, somebody else might help you with the rest of the question. Bye
