英文摘要： Spatial modulation (SM) is a new class of multiple-input multiple-output (MIMO) transmission techniques, which utilizes the index of the active transmit antennas as a means of conveying source information. The SM-based cooperative relay system is capable of inheriting the benefits of low computational complexity, low realization cost as well as flexible transceiver antenna configurations of SM, while improving the ubiquitous coverage or the reliability of transmission network. It constitutes a promising transmission candidate for future wireless applications..In this project，we will study link adaptation theory and techniques for the SM-based cooperation relay networks. Firstly, we will investigate the transmission theory of the SM-based relay cooperation, and drive its performance metrics, i.e., the ergodic capacity, the outage probability and the bit error ratio (BER). Then, based on these theoretical results, we will focus our attention on various link adaptation algorithms, such as the relay selection algorithms and the power allocation algorithms, for achieving system performance improvement. Finally, we will consider the joint design of these algorithms for achieving multi-domain collaborative optimization. Through these research works, the complete adaptive SM-based cooperative relay communication theory and technique systems will be established. The related research results are capable of applying to the next generation wireless communication, hence have both theoretical and economical importance.
