6.15 Determine the transmission bandwidth reduction and average signal energy of 256-QAM, compared to 64-QAM. 6.16 Two passband data transmission systems are to be compared. One system uses 16-PSK, and the other uses 16-QAM. Both systems are required to produce an average probability of symbol error equal to 10-3. Compare the signal-to-noise ratio requirements of these two systems.
