Q15) A QPSK modulation scheme transmits the carrier cos(2nfct + 0) where each symbol, i.e., an information bit pair, is mapped to its respective phase angle according to the rule: Information bits: “00” “01” "11" "10" 1 1 1 + Phase angle, 8: 0 1/2 π 31/2 Suppose the symbol sequence in Fig. Q15 was transmitted. Here T is the symbol duration. Fig. 215 WWWMW 0 T T T T Recover the eight information bits from the above symbol sequence. [5 marks]
