2. (10pts) Suppose the binary bit stream "10110101" is sent using w/4-DQPSK, with the left most bits applied to the transmitter first. The two QPSK constellations are shown in Fig. 2. The bit mapping is given in Table 1. Assume using Fig. 2(a) as the starting QPSK constellation. Assuming that Oo-0. i) Determine the carrier phase 0, the in-phase component / and the quadrature component Qk, for the input sequence. ii) Specify in sequence the constellation symbols used to transmit the input sequence (specify which QPSK constellation, e.g. for r₁ in (a), write (a)). 32 "01" "00" 23 "11" "10" @ "01" Figure 2: Problem 2 (mik, mok) 00 01 /4 3/4 TA 11 10 Table 1: 5л/4 7/4 "00" (b) "10"
