DCT/IDCT-based interpolation for channel estimation in OFDM systems(OFDM系统DCT/IDCT插值信道估计算法)

DCT/IDCT-based interpolation for channel estimation in OFDM systems(OFDM系统DCT/IDCT插值信道估计算法)

导频辅助信道估计是OFDM系统常用的信道估计算法，本文研究基于变换域的导频辅助信道估计算法.在DFT插值法的基础上，提出了基于离散余弦变换(DCT)的信道估计方法.仿真结果表明，该插值算法的MSE和SER性能优于DFT方法.与MMSE算法相比，该插值算法计算复杂度低，易于物理实现....
