基于SCKF的OFDM信道估计算法研究
Research on OFDM Channel Estimation Based on SCKF
摘要
Abstract
The OFDM technique has the advantage of anti-muhipath and sufficiency of the channel band application. But with the increase of the transmission distance, the deteri0rism of channel conditions, and the severe influence of doppler frequency shift, the communication transmission of OFDM becomes more and more difficult, so it has important significance to research effective channel estimation algorithm. A new nonlinear-filter algorithm Square-Root Cubature Kalman Filter （SCKF） is offered for channel estimation, and then the algorithm can realize the accurate estimation of OFDM channel by the channel recursion of the OFDM subcarrier. Compared with the Least-Squares （LS） channel estimation algorithm and Discrete Cosine Transform （DCT） channel estimation algorithm, the new algorithm has the better anti-noise performance by experiments.关键词
