a.) The average signal power is Ps What is the minimum distance d for each signal constellation 1-4? b.) Let the noise power PN be a constant. Sort the constellations 1-4 on signal-to-noise ratio Ps and express the differences in signal-to-noise ratios in decibels. PN c.) Assume that the real and imaginary parts n and no of the noise are independent. In d d d d P (n < 1) = P (nq < ) = P ( > 1 ) = P ( no > =/ ) = > =p 2 2 addition let P < where the minimum distance d is the same for all constellations 1-4.
