Assume equal prior probabilities and perfect phase and frequency synchronization in the coherent detection. a) Find the general form of error probability as a function of . Assume the noise variance is /2 and signal energy is . b) For 1/5 and / 10 , find and compare it to the case when 0. c) When 1/5, how much in dB should you increase the signal energy () to achieve the same error probability as when 0 and / 10 ? (You may need a computer to find the answer.)...
