摘要

本文研究了长期演进(LTE)接收机在频分双工(FDD)模式下的几种信道估计方法。仿真结果表明，二维8符号线性估计对仿真信道是足够的。复杂度较高的方法，如二维三次卷积插值和分段三次Hermite插值多项式(PCHIP)并没有明显优于线性插值。

Comparative study of channel estimation methods for LTE downlink transmission

This paper studies several channel estimation methods for LTE (Long Term Evolution) receivers in the FDD (Frequency-Division Duplexing) mode. The simulation results show that a 2-D 8-symbol linear estimation is sufficient for simulated channels. Higher complexity methods such as 2-D cubic convolution interpolation and piecewise cubic Hermite interpolating polynomial (PCHIP) do not significantly outperform the linear interpolation.
