% Demodulates a complex-baseband phase shift keying modulated signal
% into an information sequence of integers in the range
% @code{[0 @dots{} M-1]}. @var{phi} controls the initial phase and
% @var{type} controls the constellation mapping. If @var{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
%
% @example
% @group
% 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)
