Create a Matlab Monte Carlo simulation for 4-QAM (QPSK) (Monte Carlo simply means repeated trials of a probabilistic experiment). Make this a baseband simulation, using the signal space with signal points at locations /4, with n{1, 3, 5, 7}. Use one sample per symbol, and Gray encoding and decoding to enable estimation of symbol error probability PM and bit error probability Pb. (a) (5 points) Describe how your simulation works. Provide a block diagram that describes all the operations of the simulation. (b) (10 points) Plot the analytical and simulated curves for both symbol and bit error probability all on the same graph (total of 4 curves), vs. Eb/N0 in dB, for Eb/N0 from 0 to 8 dB with steps of 0.5 dB. Hint: recall for QPSK exact analytical symbol error probability we have =2(2E)[11(2E)]. 0 2 0
