摘要
对OFDM系统中基于导频辅助的信道估计算法进行了研究,重点介绍了各种插值算法,并通过Matlab仿真对各种算法的性能进行比较,最后对基于FFT时域插值算法进行了改进。
The pilot-assisted OFDM channel estimation algorithms are investigated with the emphasis on some interpolation algorithms and the performance evaluation of each algorithm is given by Matlab. A new improved interpolation algorithm based on FFT time-domain is presented and this algorithm shows an excellent performance.
