摘要
信道估计从大的角度可以分为非盲估计和盲估计以及在此基础上产生的半盲估计。半盲估计在数据传输效率和收敛速度之间做一个折中,即采用较少的训练序列来获得信道的信息。文章详细介绍了基于子空间分解的半盲信道估计的算法。
Channel estimation can be classified into semiblind channel estimation, blind channel estimation, and semi_blind channel estimation derived from the first two. By trading off the data transportation efficiency and convergence rate, the semiblind channel estimation adopts fewer training sequence to acquire the channel information. The paper describes in detail the semi_blind channel estimation algorithm based on subspace identification.
