Comaprison on 2 files

[Maitry]

Hello support team,

I have 2 different file for which i need to compare the number of error bits for ultimate BER comparison.
I have tried attached MATLAB code. My Tx file is 1.txt. But when I import the 1.txt file in matlab as per written code. MATLAB is not properly understand the 1.txt file. But when I import the file like txdata1.txt , then it import as per required. As you can see, my file 1.txt is too big. Is there something I am doing wrong. plz guide. I want to import the file like 1.txt(transmitted file ) and similar received file (with some errors) . How can I compare the file like this(1.txt ) with the similar file(with errors)

Awaited your guidance.

Hi,

txdta1.txt shows a bitstream where each bit is a vector element (each bit in a separate row), in 1.txt your bit stream is a single number (no delimiter e.g. newline, between the individual bits), which is too large to be handled by MATLAB.

For a "low" value this should work [1]. It seems your bitstream is to long to result in a single integer.

This simple code should help to convert your single "value" (column, row) file into a vector.

d = fopen('1.txt'); 
data = textscan(d,'%s','delimiter','\n'); 
fclose(d);

data = data{1};

N = 5E5; % number of bits representing your single value

for ii=1:N
   x(ii) = str2double(data{1}(ii));
end
