I want to draw the complex-valued baseband signal with real $S_{BB,I}(t)$ and imaginary part $S_{BB,Q}(t)$ for the following bit sequence: 011111001000
I have looked around and found on wikipedia such a timing diagram but for QPSK:
I understand that the bit sequence of a QPSK is grouped in pairs of two, the first bit of the pair is assigned to I, the second part of the pair is assigned to Q. If I=1, the sine starts at the top. If Q=1, the cosine rises.
How would I need to draw this diagram for an 8-PSK? The bits are grouped in pairs of three. So my bit sequence is 011
,111
,001
,000
. I am puzzled how to assign the pairs of three to only two signals I and Q.
