Abstract
Provided is a wireless communication apparatus, comprising: a symbol synthesis circuit that synthesizes received symbols; a demodulation circuit that demodulates the received symbols each before and after the synthesis; an error correction circuit that corrects demodulated received data from the demodulation circuit; a detection circuit that detects a first error detection code from the error corrected received data; a second detection circuit that detects a second error detection code obtained by inverting a plurality of arbitrary bits from the error corrected received data; a received data selection circuit that selects the received data, wherein: the received data selection circuit determines a modulation scheme used upon transmission by using detection results of the first and second error detection codes and selects received data corresponding to the determined modulation scheme.
