Q2) A communication system employs 8-ary ASK modulation. The symbols are represented by the signals A cos(21fct) V. The symbol duration is T = 5 x 10-4 s and the channel is AWGN. (a) Consider the two schemes below. Scheme 1: A = +1, +3, +5,27 and Scheme 2: A = 1,3,5,7,9, 11, 13, 15. What is the BER for Scheme 2 if the BER for Scheme 1 is 10-57 [3 marks] (b) Calculate E (average energy per bit), respectively, for both schemes in (a). [3 marks] (As always, assume a 1. load resistance.)
