In 4-PSK (or QPSK), information carried by the transmitted signal is contained in the phase.
1) Write the definition of the transmitted signals si(t) in 4-PSK for the interval 0 t T where i = 1, 2, 3, 4.
2) Draw the signal constellation with Gray coding for 4-PSK modulation.
3) ) Explain why the above Gray coding for 4-PSK modulation is optimum.
4) Draw the signal constellation with Gray coding for 8-PSK modulation.
