| 摘 要： | 设计了多天线认知无线电系统上行信号处理算法.该算法考虑移动终端尺寸、复杂度方面的约束,由认知基站完成接收波束成形及干扰抑制,认知终端仅进行发射波束成形,降低了终端复杂度,便于系统实现.在此基础上提出基于空分复用的机会频谱接入方法,认知系统通过合理的天线配置,当无法获得空闲频谱资源时以空分复用方式完成通信,并且保证对授权...

| Abstract: | A signal processing algorithm for uplink transmission in multi-antenna cognitive radio system was designed,in which the equipment size and complexity constraints of the mobile station were considered.The cognitive base station carried out receiving beamforming and interference elimination,whereas cognitive terminal implemented transmitting beamforming only.The complexity of cognitive terminal was reduced and the system implementation was facilitated.Based on the above work,an opportunistic spectrum access s... |
