摘要
In this brief, a new differentially spatial modulated chaos shift keying modulation communication system is proposed, in which the transceiver has not accessed channel state information. In the transmitter, the symbol can be mapped into the dependently selected antenna by the differential matrix in each interval. Meanwhile, in the receiver, the maximum received signal is used to retrieve the block of transmitted bits by the maximum likelihood estimation. By employing the spatial modulation, the proposed scheme offers a higher spectrum efficiency and the energy efficiency compared to the conventional multiple-input multiple-output differential chaos shift keying system. Lastly, the theoretical upper bounds on the average bit error probability, analyzed and derived, are in good agreement with the simulation results.
