Data relaying apparatus, communication apparatus, and data relaying method

摘要

A data relaying apparatus for relaying data bidirectionally transmitted between a first communication apparatus and a second communication apparatus includes a first symbol string generator configured to generate, in accordance with a first modulation method, a first symbol string from first data transmitted from the second communication apparatus; a second symbol string generator configured to generate, in accordance with a second modulation method, a second symbol string from second data transmitted from the first communication apparatus; and a combining unit configured to combine a first symbol of the first symbol string and a second symbol of the second symbol string by calculating an exclusive OR on the first symbol and the second symbol to generate a third symbol string to be multicasted to the first communication apparatus and the second communication apparatus.
