I am working in a project and I do not know how to get the BER between my orignal image and the one received.
so basically If do this
I should get zero ber but this method is not working for me and i am getting an error message. Can somebody help please.

You are receiving this error because your inputs are 3-dimensional, while BITERR works at most with 2-D data.
More important, BITERR works with the equivalent binary representation. For example,
>> biterr(8, 7)
because 8 = 1000 and 7 = 0111, therefore all 4 bits are different.
Is this what you want? Or do you want to count the number of "pixels" that are different? If your goal is the latter, then you can use this code:
>> sum( sum( A ~= B ) ) / numel(A)
which counts the number of differing numbers and calculates their ratio.
