ABSTRACT:
An object of the invention is to provide a wireless communication apparatus which can correct error flexibly without wasting consumed resources while maintaining the improvement of reliability resulted from error correction. The wireless communication apparatus (relay station)12includes a receiving antenna41for receiving signals transmitted from the transmission station, a receiving RF section42for high-frequency amplifying the received signal, an error correction decoding section43for subjecting the received signal to the error correction decoding processing and outputting soft decision values and decoded bits, an error detection section44for subjecting the signal after the error correction decoding processing to the hard decision processing to detect error of the signal subjected to the hard decision processing, a switching section45for switching the soft decision values and the decoded bits, a re-coding section46for re-coding extracted ones of the soft decision values, a transmission RF section47for modulating the re-coded soft decision values and a transmission antenna48for transmitting the signal to the receiving station.
