Optimal Estimation of Sensor Biases for Asynchronous Multi-Sensor Data Fusion
Wenqiang Pu, Ya-Feng Liu, Junkun Yan +2
An important step in a multi-sensor surveillance system is to estimate sensor biases from their noisy asynchronous measurements. This estimation problem is computationally challeng…
Joint Power and Admission Control based on Channel Distribution Information: A Novel Two-Timescale Approach
Qitian Chen, Dong Kang, Yichu He +2
In this letter, we consider the joint power and admission control (JPAC) problem by assuming that only the channel distribution information (CDI) is available. Under this assumptio…
Joint Power and Admission Control: Non-Convex Approximation and An Effective Polynomial Time Deflation Approach
Ya-Feng Liu, Yu-Hong Dai, Shiqian Ma
In an interference limited network, joint power and admission control (JPAC) aims at supporting a maximum number of links at their specified signal to interference plus noise ratio…
Base Station Activation and Linear Transceiver Design for Optimal Resource Management in Heterogeneous Networks
Wei-Cheng Liao, Mingyi Hong, Ya-Feng Liu +1
In a densely deployed heterogeneous network (HetNet), the number of pico/micro base stations (BS) can be comparable with the number of the users. To reduce the operational overhead…
Joint power and admission control via p norm minimization deflation

Sample Approximation-Based Deflation Approaches for Chance SINR Constrained Joint Power and Admission Control
Ya-Feng Liu, Mingyi Hong, Enbin Song
Consider the joint power and admission control (JPAC) problem for a multi-user single-input single-output (SISO) interference channel. Most existing works on JPAC assume the perfec…
Decomposition by Successive Convex Approximation: A Unifying Approach for Linear Transceiver Design in Heterogeneous Networks
Mingyi Hong, Qiang Li, Ya-Feng Liu
We study the downlink linear precoder design problem in a multi-cell dense heterogeneous network (HetNet). The problem is formulated as a general sum-utility maximization (SUM) pro…
