Abstract
Channel estimation algorithms are employed in 3GPP Long Term Evolution (LTE) downlink system to help with coherent demodulation. Several CRS-aided channel estimation algorithms over multipath Rayleigh fading channel have been investigated in this paper. Based on theoretical analysis and simulation, Wiener interpolation channel estimator is proposed for LTE downlink system. In consideration of practical implementation and universality for different channels, we propose that CRSs in Wiener interpolation should be contained in the time window of 10eāā3 second as well as in the frequency window of two adjacent resource blocks, which symmetrically distribute around the current estimated resource block in frequency domain.
