Method and apparatus for minimizing interference co-channel

A method for minimizing co-channel interference in a digital broadcasting system (100), the method comprising the steps of: encoding a header (401) of a first frame based on a first unique word (411, 413); and encode a header (401) of a second frame based on a second unique word (411, 413), wherein the first frame including the corresponding encoded header (401) and the second frame including the corresponding encoded header (401 ) are transmitted, respectively, by adjacent co-channels of the communication system (100).
