Dear All,

I doing a test on the IEEE 802.11a model that is in simulink, and I want to compare the input of the wireless connection with the output to find what is the packet error rate and the bit error rate when applying different conditions on the wireless connection.

I was able to save the input and the output (as binary code) of the wireless connection in two different mat files as 1036800x1 double array, so what is the best way to compare these two files together "bit by bit" and if they match I want to keep it 0 and if not to make it 1 and save the result in another array.

or if there is another way in simulink that can give record the input and output and compare them directly and get me what I am looking for.

hope that I can get a solution for my problem.

Thx

Rami,

You should load the .mat files in MATLAB
Once you have the vectors in variables, say x and y you should do the following:

To know whether they differ type:
>> ~all(x == y)

This will return 0 if equal, 1 otherwise

To know indexes where vectors differ type:
>> z = x == y
>> find(~z)
