摘要

经典的信道估计器是基于导频符号辅助调制的线性插值器。由于信道变化率与其最大多普勒频移有关，因此可以通过估计的多普勒频移来确定插值长度，因此可以采用自适应加权多时隙平均信道估计方法来提高信道估计精度。仿真结果表明，该方法在较宽的速度范围内具有良好的性能。

Adaptive WMSA channel estimation based on Doppler shift estimation in CP-SCBT systems

The classical channel estimator is a linear interpolator based on PSAM (pilot symbol assisted modulation). The interpolation length can be determined by the estimated Doppler shift because the channel variation rate is related to its maximum Doppler shift, which leads to an adaptive WMSA (weighted multislot average) channel estimation method to improve channel estimation accuracy. Simulation results show good performance in a wide range of velocities.
