Binary symmetric channel problems
WebThe binary symmetric channel (BSC) with crossover probability p, shown in Fig. 6, models a simple channel with a binary input and a binary output which generally conveys its … 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.

Webreliability function of the channel). In particular, we prove that the “random coding exponent” is the true value of the channel reliability for codes rate in some interval immediately below the critical rate of the channel. An analogous result is obtained for the Gaussian channel.

It was introduced by Elias as a toy example in 1954. The …
WebThe channel capacity theorem also holds for continuous valued channels, which are very important in a number of practical scenarios, e.g., in wireless communication. But before studying such channels, we need to extend notions like entropy and mutual information … WebProblem 1 Encoder and decoder as part of the BSC channel: Consider a binary symmetric channel with crossover probability (P_error) 0.1. A possible coding scheme for this channel with two code words of length 3 is to encode message a1 as 000 and a2 as 111. With this coding scheme, we can consider the combination of
