Consider the following 16 signal vectors s0= (-3,0), s1 =(-1,0), s2= (+1,0), s3=(+3,0) s4=(-2, sqrt(3)), s5=(0,sqrt(3)), s6=(+2,sqrt(3)), s7=(+4,sqrt(3)), s8=(-1,2*sqrt(3)), s9=(+1, 2*sqrt(3)), s10=(-4,-sqrt(3)), s11=(-2,-sqrt(3)), s12= (0,-sqrt(3)), s13=(+2,-sqrt(3)), s14=(-1,-2*sqrt(3)), s15=(+1,-2*sqrt(3)) . (a) calculate the Euclidean distance between every pair of distinct signals and the minimum Euclidean distance between distinct signals. (b) calculate the average energy per information bit, Eb. (c) calculate the normalized squared Euclidean distance. (d) calculate the PAPR Tv for this constellation
