| 摘 要： | 研究了信道FIR模型,提出用信道模式集仿真实际的时变信道,并在此基础上设计一种基于MMSE准则的完全盲信道估计算法,并将其应用于一个四进制通信系统仿真.仿真结果表明:新算法效果十分理想,当信噪比在6db时误码率接近0.

| Abstract: | The channel FIR model was investigated to simulate time-varying channels with a set of chan- nel models,and then, based on the MMSE criterion, a new method of blind channel estimation was de- signed. The method was applied to the simulation of a quaternary communication system. The simulation result shows that the new method is of high property,and the ECR is close to zero when the signal-to-noise ratio is about 6db. |
