theta_i.m

Describes how to find the theta value in CPFSK

function theta = theta_i(In_Sig,h)

% To find the Theta_i value to compute the Mean Value
theta = 0;
for j=1:length(In_Sig-1)
% check the bit is either 0 or 1
    if In_Sig(j)== 1
        Aj = 1;   % If one then Aj will be 1
    elseif In_Sig(j) == 0
        Aj = -1;  % If one then Aj will be -1
    end;
%Calculate the Theta_i value

    theta = theta + (pi*h*Aj);
end
