WebAn (n + u, k) linear code generated by adding u check symbols to an (n, k) linear code is called an extended code of the original code. In particular, if we add a check bit to a binary ( n, k ) code with an odd minimum distance d so that the number of 1's in each codeword is even, we obtain an ( n + 1, k ) extended code with minimum distance d + 1. Weberator by processing based on binary linear codes. We introduce a new bound on the total variation distance of the processed output based on the weight distribution of the code generated by the chosen binary matrix. Starting from this result we show a lower bound for the entropy rate of the output of linear binary extractors. 1 introduction
