Robust Receiver Design for Non-orthogonal Multiple Access
Kun Wang
Non-orthogonal multiple access (NOMA) has been proposed for massive connectivity in future generations of wireless communications. A dominant NOMA scheme is based on power optimiza…
Joint Receiver Design for Internet of Things
Kun Wang
Internet of things (IoT) is an ever-growing network of objects that connect, collect and exchange data. To achieve the mission of connecting everything, physical layer communicatio…
Unified Receiver Design in Wireless Relay Networks Using Mixed-Integer Programming Techniques
Kun Wang
Wireless receiver design is critical to the overall system performance. In this work, we apply the techniques of mixed-integer programming to formulate a unified receiver in relay…
Ricean K-factor Estimation based on Channel Quality Indicator in OFDM Systems using Neural Network
Kun Wang
Ricean channel model is widely used in wireless communications to characterize the channels with a line-of-sight path. The Ricean K factor, defined as the ratio of direct path and…
Semidefinite Relaxation Based Blind Equalization using Constant Modulus Criterion
Kun Wang
Blind equalization is a classic yet open problem. Statistic-based algorithms, such as constant modulus (CM), were widely investigated. One inherent issue with blind algorithms is t…
Expressway visibility estimation based on image entropy and piecewise stationary time series analysis
Xiaogang Cheng, Guoqing Liu, Anders Hedman +2
Vision-based methods for visibility estimation can play a critical role in reducing traffic accidents caused by fog and haze. To overcome the disadvantages of current visibility es…
