Blind Channel Estimation for MIMO-OFDM System Based on Oblique Projection
Zhiyong Zhang, Jifeng Sun · 2009
The blind channel estimation using oblique projection of MIMO-OFDM system is proposed in this paper. It is introduced firstly of the channel model and receiving-data model. The fundamental principle of oblique projection is considered roughly and the oblique projection algorithm on how to estimate the channel matrix and the ambiguous matrix are both particularly analyzed. The simulation results show that the estimation performance of the oblique projection algorithm with lower computational complexity is close to that of subspace decomposition algorithm.
