摘要主要讨论能够进一步提升多天线系统容量的闭环MIMO技术,即带有反馈的MIMO系统。给出了几种在未来无线通信系统中可能采用的闭环MIMO方案,分析并比较了它们的性能。仿真结果表明,闭环MIMO技术将有效地提高通信系统的性能。 Closed MIMO techniques, with feedback information in wireless links, can further enhance the capacity of wireless communication systems. It gives several possible solutions of closed MIMO schemes and compares their performance with different parameters. The performance of the closed MIMO schemes is validated by computer simulations.
