Unraveling the Rank-One Solution Mystery of Robust MISO Downlink Transmit Optimization: A Verifiable Sufficient Condition via a New Duality Result
Wing-Kin Ma, Jiaxian Pan, Anthony Man-Cho So +1
This paper concentrates on a robust transmit optimization problem for the multiuser multi-input single-output (MISO) downlink scenario and under inaccurate channel state informatio…
Multiuser One-Bit Massive MIMO Precoding Under MPSK Signaling
Mingjie Shao, Qiang Li, Yatao Liu +1
Most recently, there has been a flurry of research activities on studying how massive MIMO precoding should be designed when the digital-to-analog conversion at the transmitter sid…
Semidefinite Relaxation and Approximation Analysis of a Beamformed Alamouti Scheme for Relay Beamforming Networks
Sissi Xiaoxiao Wu, Anthony Man-Cho So, Jiaxian Pan +1
In this paper, we study the amplify-and-forward (AF) schemes in two-hop one-way relay networks. In particular, we consider the multigroup multicast transmission between long-distan…
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…
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…
The Equivalence of Semidefinite Relaxation MIMO Detectors for Higher-Order QAM
Wing-Kin Ma, Chao-Cheng Su, Joakim Jalden +2
In multi-input-multi-output (MIMO) detection, semidefinite relaxation (SDR) has been shown to be an efficient high-performance approach. Developed initially for BPSK and QPSK, SDR…
