WebMay 31, 2013 · I am working through Cover, Thomas "Elements of Information Theory" and want to try and implement a simple example of a binary symmetric channel. That is to say, I can specify a message "1001", an encoding "11000011" (basically repeat each bit twice), a channel law: p(y x), and I'd like to see my posterior at the receiver update. WebThe Err port for the Binary Symmetric Channel is a binary vector whose length matches the total number of samples processed. By summing the elements of the output Err vector you get the total number of errors introduced into the signal data. The sum of the elements of the Err vector is saved to the base workspace variable BscErrTotal. 卵生 胎生とは https://sexycrushes.com
