Abstract (in Japanese) (See Japanese page) 
(in English) The easiest way to improve transmission efficiency for MIMO(Multiple Input Multiple Output) that is a communication system with some transmitting and receiving anntenas is increasing the number of transmitting and receiving anntenas. Those systems by using about 10 to 100 antennas are called massive MIMO, we expect that it improves transmission efficiency drastically. In this paper, we study the decoding problem in massive MIMO that adapted chaos modulated in ordar to obtain security. We evaluate performance of BP(Belief-Propagation) method which enables to decode in a realistic computational time.
We have found that tends to be high BER(Bit Error Ratio) when chaos-modulated signals are introduced.
