ABSTRACT:
A method and apparatus is disclosed by which communication with a higher degree of accuracy can be achieved with increased easiness. A transmission apparatus transmits base data formed by dividing transmission data and redundant data produced by exclusive OR operation using a coefficient matrix prepared in advance to a reception apparatus. The base data and the redundant data have restoration relating information relating to a restoration process added thereto. The reception apparatus specifies lost base data based on the information added to the received base data and redundant data and aligns the acquired redundant data. The reception apparatus utilizes a coefficient matrix prepared in advance to perform exclusive OR operation to restore the lost base data and produces reception data corresponding to the original transmission data. The apparatus and method can be applied to a communication system.
