Joint DOA and channel estimation with data detection based on 2D unitary ESPRITin massive MIMO systems Article

Jing-ming KUANG, Yuan ZHOU, Ze-song FEI

Frontiers of Information Technology & Electronic Engineering 2017, Volume 18, Issue 6,   Pages 841-849 doi: 10.1631/FITEE.1700025

Abstract: The conventional DOA estimation algorithms usually assume that the channel impulse responses are knownimpulse responses.In contrast, a joint DOA and channel estimation scheme is proposed, which first estimates the channelimpulse response estimates instead of accurate channel impulse responses and then, the enhanced channelimpulse response estimates can be obtained.
