Communications Toolbox

Creating the Signal

The variable signal is a len-by-1 matrix, that is, a column vector of length len, whose entries are randomly chosen integers between 0 and M-1. This is the signal that the example will modulate. The randint function is part of this toolbox.

• % Create a signal.
  signal = randint(len,1,M); % Random digital message
  % consisting of integers between 0 and M-1
