Title:
WIRELESS COMMUNICATION METHOD AND WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/168821
Kind Code:
A1
Abstract:
According to the present invention, a demodulator demodulates a wireless signal by using a priori information, and outputs first bit information. An interleaver executes, with respect to the first bit information, a de-interleaving process for restoring, to original order, the order of bits switched by an interleaving process for switching the order of the bits, and outputs second bit information. A decoder decodes the second bit information, and outputs third bit information. A deinterleaver executes, with respect to the third bit information, an interleaving process reverse to the de-interleaving process to generate fourth bit information, executes an iterative decoding process by inputting the fourth bit information to the demodulator as the a priori information. A code optimization unit generates redundancy bit control information on the basis of likelihood information obtained during the iterative decoding process, and notifies a transmitter of the generated control information. The transmitter transmits an additional redundancy bit on the basis of the generated control information.
