| 摘 要： | 空间分集与编码调制技术相结合的空时编码技术,可以获得分集和编码增益,具有优异的抗衰落性能。传统空时编码和多输入多输出(MIMO)技术是通过多天线来实现空间分集的,但是由于移动台的尺寸和载频的限制,使多天线技术很难实现。基于复杂系统自组织MIMO无线传输分集和编码技术成为解决这一问题的可选方案,并且无需通过信道反馈信息,动态分配资源,提高了端到端的通信服务质量(QoS)和信道容量。

| Abstract: | Space-time coding technolgy is proposed by combing space diversity and coding modulation technology to obtain diversity and coding gain,and excellently resist fading performance.Traditional space-tiem coding and Multiple-Input Multiple-Output(MIMO) technique exploit space diverisity through multple transmit receive antennas.However,due to the size of a mobile and carrier frequency consrraints,achieving space diverisity though multiple antennas may not be possible.Cooperative deversity has recently emerged as an alternative way to achieve diversity and coding gain,which has not feedback of Channel State Information(CSI),dynamic resource allocation is proposed,and also improve end-to-end communication quality of service and channel capacity. |
