N2 - Higher order modulation and spatial modulation schemes improve the data rate for differential chaos shift keying (DCSK) systems by transmitting more bits in one time slot, however, the reliability performances become worse respectively due to more dense signal distributions and bad channel condition of active antenna. In this paper, we propose to utilize the antenna and symbol indexes to improve both the data rate and the reliability performances for DCSK systems with aid of antenna selection. Therein the information is modulated cooperatively using the antenna index and the symbol index. Then with the aid of the feedback channel state information (CSI) from receivers, the antenna with the best CSI is selected to transmit modulated symbols, which helps to improve the reliability performance. At the receiver, reverse operations are performed. Furthermore, we provide the theoretical symbol error rate (SER) and bit error rate (BER) over the multi-path Rayleigh fading channel. Simulation results demonstrate that the proposed scheme achieves better reliability performances than the counterpart schemes with the same data rate.
