Q13) A QPSK modulation scheme transmits the carrier cos(2nfet + 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" + Phase angle, e: 0 TT/2 TI Зп/2 Suppose the symbol sequence in Fig. 213 was transmitted. Here T is the symbol duration.

Fig. 213 T 2T 37 4T Recover the eight information bits from the above symbol sequence. [5 marks)
