wow, your code is quite difficult to read. It would be nice if you'd clean it up when you ask for some support. 

It seems you read lines in from a file and put then into an integer array: Integer is often default a 32-bit signed value. You then cast the integer value into an unsigned 8-bit bit-vector. Could it be that something already goes wrong with the type conversion? The code is missing the implementation of LFSR and Embedding_Module. Also: "endoffile" and "linenumber" seem unused.
