14. A digital communication system transmits data using QAM signaling over a voice- band telephone channel at a rate 2400 symbols/s (baud). The additive noise is assumed to be white and Gaussian. You are asked to determine the energy-per-bit-to-noise ratio Eb/NO required to achieve an error probability of 10-5 for a bit rate equal of 4800 bits/s. Use the following expression for the error probability of an M-ary QAM system: PM4Q Q(x) e-.) 30Eb (M-1) No
