Compressed downlink channel acquisition based on burst support information in large‐scale MIMO systems
In this Letter, a compressed channel estimation approach referred to as burst weighted ℓ1‐minimisation is proposed to alleviate the overwhelming pilot overhead in the downlink path of frequency division duplex (FDD) massive MIMO systems. The proposed approach exploits the burst‐sparse property of ch...
