Demodulates a complex-baseband phase shift keying modulated signal
into an information sequence of integers in the range
[0 … M-1]. phi controls the initial phase and
type controls the constellation mapping. If type is set
to "Bin" will result in binary encoding, in contrast, if set to
"Gray" will give Gray encoding. An example of Gray-encoded 8-PSK is
d = randint (1, 1e3, 8); y = pskmod (d, 8, 0, "gray"); z = awgn (y, 20); d_est = pskdemod (z, 8, 0, "gray"); plot (z, "rx") biterr (d, d_est)
