Abstract: PROBLEM TO BE SOLVED: To provide devices and a method of transmission designed to reduce the error occurrence in a communication system. SOLUTION: A diffuser (216) is provided with a code generator (301) and an exclusive OR circuit (303). As a good example of how this invention works, the code generator (301) generates a code having length and value which are dependent on the current transmission rate. Then, this code XORs with the coming data stream to generate diffused data.
