Self-Supervised Point Cloud Registration with Deep Versatile Descriptors

no code implementations25 Jan 2022 Dongrui Liu, Chuanchuan Chen, Changqing Xu, Robert Qiu, Lei Chu

In this paper, we propose to jointly use both global and local descriptors to register point clouds in a self-supervised manner, which is motivated by a critical observation that all local geometries of point clouds are transformed consistently under the same transformation.

Efficient Nonlinear Precoding for Massive MU-MIMO Downlink Systems with 1-Bit DACs

1 code implementation24 Apr 2018 Lei Chu, Fei Wen, Lily Li, Robert Qiu

The power consumption of digital-to-analog converters (DACs) constitutes a significant proportion of the total power consumption in a massive multiuser multiple-input multiple-output (MU-MIMO) base station (BS).
