Abstract :
On the basis of analysis to MIMO-OFDM system, the paper use the characteristic of the time domain channel energy concentrated on relatively small number of sampling points to improve the estimation algorithm, and use singular value decomposition (SVD) to give a low-level channel estimation algorithm. Simulation results show that the improved algorithm has better estimation performance and low computational complexity.
