英文摘要： How to improve the communication link rate and the reliability for underwater platforms is an urgent task for the researchers all around the world. Aim at the reliable and high-rate underwater acoustic communication for small size platforms, we propose spatial modulation based MIMO communication method in this project on our research baisis for SIMO high-rate underwater acoustic communication. Key technologies for spatial modulation communication will be studied including extended rate transmitter design and optimization, compressive sensing channel estimation for spatial modulation and kinds of low complexity detector algorithms in double selective fading channels. The proposed methods will be verified and improved by tank, and lake experiments. The processing software system of MIMO communication will be founded and investigated to provide powerful support to research. The research in this project can significantly improve the bandwidth efficiency of underwater communication system on small size underwater platforms, and also provide a novel solution for high-rate reliable underwater communication.The achievements of this project have important meaning and extensive application value to the development of underwater acoustic communication systems, underwater sensor network and ocean monitoring.
