Abstract-The security of chaos communication system is superior to other digital communication system, because it has characteristics such as non-periodic, wide-band, nonpredictability, easy implementation and sensitive initial condition. However, chaos communication system increases the number of transmitted symbols by spreading and transmitting information bits according to characteristic of chaos maps. So the research that improves data transmission speed is necessary for chaos communication system. If many antennas are applied to chaos communication system, the capacity of data is proportional to the number of antenna.so it is good way applying multiple-input and multiple-output (MIMO) to the chaos communication system. In this paper, we propose the correlation delay shift keying (CDSK) using 2´2 MIMO technique and evaluate BER performance over Rayleigh MIMO fading channel. Lastly we evaluate BER performance applying the boss map with 2x2 MIMO using MIMO detection algorithm such as zero forcing (ZF) and minimum mean square error (MMSE).

Abstract-Chaos communication system has characteristics of non-periodic, non-predictability, broadband signal and easy implementation. Also, the characteristic of chaos communication system is decided by initial values. And it has the sensitive characteristic according to initial values. Due to these characteristics, security of chaos communication system is generally better than other digital communication system. But BER(Bit Error Rate) performance is worse than digital communication system. Looking at the existing studies, chaos communication system is being studied diversity method in order to improve the BER performance in Rayleigh channel. In this paper, we apply the Alamouti STBC(Alamouti Space Time Block Coding) in order to improve the BER performance, and we evaluate BER performance of CDSK system that applied the Alamouti STBC. If we apply the Alamouti STBC to the CDSK system, we are possible to evaluate the BER performance improvement in Rayleigh channel. Therefore, if the Alamouti STBC of MIMO(Multi Input Multi Output) system applies to chaos communication system in fading channel, the deterioration of BER performance is possible to compensate. And, if you adjust number of transmitter and receiver according to kinds of channels, effective communication is possible.
