Experimental Analysis of Multipath Characteristics in Indoor Distributed Massive MIMO Channels
Yingjie Xu, Xuesong Cai, Sara Willhammar +1
Distributed multiple-input multiple-output (MIMO), also known as cell-free massive MIMO, has emerged as a promising technology for sixth-generation (6G) wireless networks. This let…
Sparse Arrays Enable Near-Field Constant-Distance Focusing with Reduced Focal Shift
Jiawang Li, Yingjie Xu, Hanieh Aliakbari
In near-field beam focusing for finite-sized arrays, focal shift is a non-negligible issue. The actual focal point often appears closer to the array than the predefined focal dista…
