NN-Based Frequency Domain DPD for OFDM Massive MIMO Transmitters With Multiple States
Yundi Zhang, Yanshi Sun, Li Chen
Frequency domain (FD)-digital predistortion (DPD) is a low-complexity DPD solution for massive multiple-inputmultiple-output (MIMO) transmitters (TXs). In this letter, we extend FD…
A Stochastic Geometric Analysis on Multi-cell Pinching-antenna Systems under Blockage Effect
Yanshi Sun, Zhiguo Ding, George K. Karagiannidis
Recently, the study on pinching-antenna technique has attracted significant attention. However, most relevant literature focuses on a single-cell scenario, where the effect from th…
Age of Information Analysis for NOMA-Assisted Grant-Free Transmissions with Randomly Arrived Packets
Yanshi Sun, Yanglin Ye, Caihong Kai +2
This paper investigates the application of non-orthogonal multiple access (NOMA) to grant-free transmissions to reduce the age of information (AoI) in uplink status update systems,…
Pinching Antennas: Principles, Applications and Challenges
Zheng Yang, Ning Wang, Yanshi Sun +5
Flexible-antenna systems, such as fluid antennas and movable antennas, have been recognized as key enabling technologies for sixth-generation (6G) wireless networks, as they can in…
Age of Information Analysis for CR-NOMA Aided Uplink Systems with Randomly Arrived Packets
Yanshi Sun, Yanglin Ye, Zhiguo Ding +2
This paper studies the application of cognitive radio inspired non-orthogonal multiple access (CR-NOMA) to reduce age of information (AoI) for uplink transmission. In particular, a…
Hybrid SIC Aided Hybrid NOMA: A New Approach For Improving Energy Efficiency
Yanshi Sun, Wei Cao, Ning Wang +2
Hybrid non-orthogonal multiple access (NOMA), which organically combines pure NOMA and conventional OMA, has recently received significant attention to be a promising multiple acce…
