摘要：In order to achieve high data rate communication with mobility, Long Term Evolution (LTE) has been introduced. LTE Downlink systems adopt Orthogonal Frequency Division Multiple (OFDM) and MIMO to provide up to 100 Mbps (assuming a 2x2 MIMO system with 20MHz bandwidth). The performance gain of MIMO heavily depends on the accurate estimation of Channel State Information (CSI), which is crucial for every communications system. In this paper, we present different channel estimation algorithms for LTE Downlink systems . This include channel estimation using Pilot Symbols and Blind Channel estimation algorithms. The estimation techniques involved the Least Square Error (LSE) and the Minimum Mean Square Error (MMSE) is being studied and finally compared
