How about the following?
% For simple example
n = 3;
m = 2;
% Create n-by-n circulant matrix
B_block = gallery('circul',1:n)';
% Create nm-by-nm block circulant matrix
B_all = repmat(B_block,m);

I believe the same approach should work, like:
% For simple example
n = 3;
m = 2;
% Create n-by-n complex circulant matrix
Re = gallery('circul',1:n)';
Im = gallery('circul',1:n)';
B_block = Re + 1i*Im;
% Create nm-by-nm block circulant matrix
B_all = repmat(B_block,m);
