Speeding-up Symbol-Level Precoding Using Separable and Dual Optimizations
Junwen Yang, Ang Li, Xuewen Liao +1
Symbol-level precoding (SLP) manipulates the transmitted signals to accurately exploit the multi-user interference (MUI) in the multi-user downlink. This enables that all the resul…
NOMA Made Practical: Removing the Receive SIC Processing through Interference Exploitation
Abdelhamid Salem, Xiao Tong, Ang Li +1
Non-orthogonal multiple access (NOMA) is a powerful transmission technique that enhances the spectral efficiency of communication links, and is being investigated for 5G standards…
Low Complexity SLP: An Inversion-Free, Parallelizable ADMM Approach
Junwen Yang, Ang Li, Xuewen Liao +1
We propose a parallel constructive interference (CI)-based symbol-level precoding (SLP) approach for massive connectivity in the downlink of multiuser multiple-input single-output…
Block-Level Interference Exploitation Precoding without Symbol-by-Symbol Optimization
Ang Li, Chao Shen, Xuewen Liao +2
Symbol-level precoding (SLP) based on the concept of constructive interference (CI) is shown to be superior to traditional block-level precoding (BLP), however at the cost of a sym…
Symbol-Level Precoding Made Practical for Multi-Level Modulations via Block-Level Rescaling
Ang Li, Fan Liu, Xuewen Liao +2
In this paper, we propose an interference exploitation symbol-level precoding (SLP) method for multi-level modulations via an in-block power allocation scheme to greatly reduce the…
Reconfigurable Intelligent Surface (RIS)-Enhanced Two-Way OFDM Communications
Chandan Pradhan, Ang Li, Lingyang Song +3
In this paper, we focus on the reconfigurable intelligent surface (RIS)-enhanced two-way device-to-device (D2D) multi-pair orthogonal-frequency-division-multiplexing (OFDM) communi…
