Joint Transceiver Design Based on Dictionary Learning Algorithm for SCMA
Shanshan Zhang, Wen Chen, Shaoyuan Chen
With the explosively increasing demands on the network capacity, throughput and number of connected wireless devices, massive connectivity is an urgent problem for the next generat…
Energy-Efficient NOMA Multicasting System for 5G Cellular V2X Communications with Imperfect CSI
Asim Ihsan, Wen Chen, Shunqing Zhang +1
Vehicle-to-everything (V2X) is a modern vehicular technology that improves conventional vehicle systems in traffic and communications. V2X communications demand energyefficient and…
Structured Distributed Compressive Channel Estimation over Doubly Selective Channels
Qibo Qin, Lin Gui, Bo Gong +2
For an orthogonal frequency-division multiplexing (OFDM) system over a doubly selective (DS) channel, a large number of pilot subcarriers are needed to estimate the numerous channe…
Block Distributed Compressive Sensing Based Doubly Selective Channel Estimation and Pilot Design for Large-Scale MIMO Systems
Bo Gong, Lin Gui, Qibo Qin +2
The doubly selective (DS) channel estimation in the large-scale multiple-input multiple-output (MIMO) systems is a challenging problem due to the large number of the channel coeffi…
Subcarrier Assignment and Power Allocation for SCMA Energy Efficiency
Samira Jaber, Wen Chen, Kunlun Wang +1
In this paper we propose resource allocation algorithm for uplink sparse code multiple access (SCMA) networks to maximize the energy efficiency (EE). Due to the joint optimization…
Generalized Quadratic Matrix Programming: A Unified Framework for Linear Precoding With Arbitrary Input Distributions
Juening Jin, Yahong Rosa~Zheng, Wen Chen +1
This paper investigates a new class of non-convex optimization, which provides a unified framework for linear precoding in single/multi-user multiple-input multiple-output (MIMO) c…
