Proximal Gradient Method for Nonsmooth Optimization over the Stiefel Manifold
Shixiang Chen, Shiqian Ma, Anthony Man-Cho So +1
We consider optimization problems over the Stiefel manifold whose objective function is the summation of a smooth function and a nonsmooth function. Existing methods for solving th…
A Framework for One-Bit and Constant-Envelope Precoding over Multiuser Massive MISO Channels
Mingjie Shao, Qiang Li, Wing-Kin Ma +1
Consider the following problem: A multi-antenna base station (BS) sends multiple symbol streams to multiple single-antenna users via precoding. However, unlike conventional multius…
Nonconvex Robust Low-rank Matrix Recovery
Xiao Li, Zhihui Zhu, Anthony Man-Cho So +1
In this paper we study the problem of recovering a low-rank matrix from a number of random linear measurements that are corrupted by outliers taking arbitrary values. We consider a…
Minimum Symbol Error Rate-Based Constant Envelope Precoding for Multiuser Massive MISO Downlink
Mingjie Shao, Qiang Li, Wing-Kin Ma +1
This paper considers the problem of constant envelope (CE) precoder designs for multiuser massive MISO downlink channels. The use of CE signals allows one to employ low-cost radio…
Phase Retrieval via Sensor Network Localization
Sherry Xue-Ying Ni, Man-Chung Yue, Kam-Fung Cheung +1
The problem of phase retrieval is revisited and studied from a fresh perspective. In particular, we establish a connection between the phase retrieval problem and the sensor networ…
On the Quadratic Convergence of the Cubic Regularization Method under a Local Error Bound Condition
Man-Chung Yue, Zirui Zhou, Anthony Man-Cho So
In this paper we consider the cubic regularization (CR) method for minimizing a twice continuously differentiable function. While the CR method is widely recognized as a globally c…
