Abstract:
1. A wireless relay station apparatus for relays between a first wireless communication apparatus and a second wireless communication apparatus, the wireless relay station apparatus comprising: a reception section that receives data from the first wireless communication apparatus and the second wireless communication apparatus; a network coding data generation section that generates network coding data using first data received from the first wireless communication apparatus and second data received from the second wireless communication apparatus, wherein the network coding data is generated by dividing each of the first data and the second data into a highly important block and a low important block and processing an exclusive OR operation between the highly important block of the first data and the low important block of the second data and between the highly important block of the second data and the low important block of the first data; a precoding section that applies a first precoding to one part of the network coding data and a second precoding to another part of the network coding data to generate precoded network coding data, the first precoding and the second precoding being different from each other; and a transmission section that transmits the precoded network coding data.
