Model of the channel with the packaged errors
by Vlad Semenov
The channel can be in two conditions: good and bad.
good - no errors. bad - errors probable

| bursterrorsstream (P, Q, E, N)

% Function of generation of a stream of the packaged errors
function [A] = bursterrorsstream (P, Q, E, N)
% P - Probability of a finding of the channel in a "good" condition
% Q - Probability of a finding of the channel in a "bad" condition
% E - Probability of occurrence of an error
% N - the Minimum size of a returned file
format long
A = zeros();
n = 0;
% While the returned file has not reached the demanded size
while n < N
n = n + 1;
b = rand(1);
% While the channel is in a "good" condition
while b < P
% We write down in a file "0"
A(n) = 0;
n = n + 1;
b = rand(1);
end
% When the channel has passed in a "bad" condition
% And if there was an error
b = rand(1);
if b < E
% We write down in a file "1"
A(n) = 1;
end
b = rand(1);
% While the channel is in a "bad" condition
while b < Q
n = n + 1;
b = rand(1);
% And if there was an error
if b < E
% We write down in a file "1"
A(n) = 1;
end
b = rand(1);
end
% When the channel has passed in a "good" condition
% We write down in a file "0"
n = n + 1;
A(n) = 0;
end
