4.9.1. Consider a non-rectangular digital QAM signal as shown. (a) Determine expressions for s0(t) through s7(t) as functions of a, φ1(t), and φ2(t). (b) Assuming all 8 signals are equally likely, determine Eavg as a function of a. (c) Determine the minimum distance between signals as a function of Eavg. How does this compare with the 8-ary rectangular QAM solved for in the notes?
