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.
