Semi_blind Channel Estimation based on Subspace Identification
Zheng Jian-hong · Communications technology · 2008
Channel estimation can be classified into semi_blind 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 semi_blind 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.
