Uplink Achievable Rate for Massive MIMO with Low-Resolution ADC
Li Fan, Shi Jin, Chao-Kai Wen +1
In this letter, we derive an approximate analytical expression for the uplink achievable rate of a massive multi-input multi-output (MIMO) antenna system when finite precision anal…
Generalized Turbo Signal Recovery for Nonlinear Measurements and Orthogonal Sensing Matrices
Ting Liu, Chao-Kai Wen, Shi Jin +1
In this study, we propose a generalized turbo signal recovery algorithm to estimate a signal from quantized measurements, in which the sensing matrix is a row-orthogonal matrix, su…
Mixed-ADC Massive MIMO Detectors: Performance Analysis and Design Optimization
Ti-Cao Zhang, Chao-Kai Wen, Shi Jin +1
Using a very low-resolution analog-to-digital convertor (ADC) unit at each antenna can remarkably reduce the hardware cost and power consumption of a massive multiple-input multipl…
Low-Complexity MIMO Precoding with Discrete Signals and Statistical CSI
Yongpeng Wu, Chao-Kai Wen, Derrick Wing Kwan Ng +2
In this paper, we investigate the design of multiple-input multiple-output single-user precoders for finite-alphabet signals under the premise of statistical channel-state informat…
Bayes-Optimal Joint Channel-and-Data Estimation for Massive MIMO with Low-Precision ADCs
Chao-Kai Wen, Chang-Jen Wang, Shi Jin +2
This paper considers a multiple-input multiple-output (MIMO) receiver with very low-precision analog-to-digital convertors (ADCs) with the goal of developing massive MIMO antenna s…
Large System Analysis of Cognitive Radio Network via Partially-Projected Regularized Zero-Forcing Precoding
Jun Zhang, Chao-Kai Wen, Chau Yuen +2
In this paper, we consider a cognitive radio (CR) network in which a secondary multiantenna base station (BS) attempts to communicate with multiple secondary users (SUs) using the…
Joint Channel-and-Data Estimation for Large-MIMO Systems with Low-Precision ADCs
Chao-Kai Wen, Shi Jin, Kai-Kit Wong +2
The use of low precision (e.g., 1-3 bits) analog-to-digital convenors (ADCs) in very large multiple-input multiple-output (MIMO) systems is a technique to reduce cost and power con…
