I think the question is pretty straightforward. I have to do a class project that requires me to modulate a signal, and one of the steps is Quadrature Phase Shift Keying (QPSK). It is to be done in the 'real life 4G LTE' method and as my professor is taking too long to respond. The message (which I have already constructed) is a series of 1s and 0s, and QPSK will take each pair of bits consecutively to turn them into symbols. I understand the math/logic of what needs to be done, but I have no idea what the constellation diagram looks like. I hope you guys can help me with this!
