New MIMO-OFDM Channel Estimation Algorithm with Low Complexity
一种低复杂度的MIMO-OFDM信道估计新方法

Based on the m-sequence,a time-domain channel estimation algorithm for Multi-Input Multi-Output Orthogonai Frequency Division Multiplexing (MIMO-OFDM) is designed.The m-sequence with Cyclic PrefLx (CP) is inserted between OFDM symbols in time domain as training sequence.The cross-correlation is calculated between the received sequence with CP removed and the appointed circular shifted m-sequence,which takes reliability of the estimation of channel impulse response on account of the two-valued auto-correlati...
