Unformatted text preview: Assume that all symbols are equally likely to be transmitted. In this case, half of the time the symbol energy will be E /2, and half of the time the energy will be 3 E /2, so the average symbol energy will be E . Assume also that symbol errors, when they occur, involve only immediately adjacent symbols, and that Gray code labeling is used so that the bit error rate will be equal to half of the symbol error rate. Plot the bit error rate for this one-dimensional system on the same graph that you used for the QPSK error plot. Comment on your results. 2 E-2 E 2 3 E 2 3 E-A B C D -2 , 2 E E 2 , 2 E E -2 , 2 E E --2 , 2 E E...
