SNR-Dependent Mismatched Filtering for Bistatic OFDM Ranging

Ying Zhang, Fan Liu, Yifeng Xiong, Jie Yang, Xinyi Wang, Shi Jin

This paper investigates the ranging performance of a bistatic integrated sensing and communications (ISAC) system employing orthogonal frequency-division multiplexing (OFDM), in which an ISAC transmitter emits a communication waveform carrying random data symbols, and a separate…

Non-Square UPA-Enabled XL-MIMO Systems: Anisotropic Near-Field Characterization, Fundamental Limits, and Channel Estimation

Yilong Liu, Xi Yang, Jing Xu, Jun Zhang, Shi jin

Extremely large-scale multiple-input multiple-output (XL-MIMO) is crucial for next-generation communication systems. In practice, the deployment of non-square uniform planar arrays (UPAs) fundamentally alters wavefront characteristics and induces anisotropic beamfocusing capabili…

Ambiguity Function Analysis of Pilot-Embedded Random OFDM Signals

Jialin Wu, Fan Liu, Ying Zhang, Yifeng Xiong, Jie Yang, Shi Jin

This paper investigates the statistical ambiguity functions (AFs) of orthogonal frequency division multiplexing (OFDM) waveforms that incorporate deterministic unit-modulus pilot symbols and random data payloads for integrated sensing and communication (ISAC). We derive analytica…

Deep Reinforcement Learning-Empowered Wireless Sensor Networking for 6G Closed-Loop Controls

Chengleyang Lei, Wei Feng, Yunfei Chen, Yongxu Zhu, Ning Ge, Shi Jin

Robots are increasingly deployed in remote or hazardous areas for mission-critical control tasks. Due to their limited individual capabilities, they have to rely on other field sensors to obtain the state information of targets, and also a dedicated edge information hub (EIH) to…

Rethinking Fractional Programming for Joint Uplink Scheduling and Power Control in Multicell Wireless Networks

Zihan Jiao, Xinping Yi, Shi Jin, Giuseppe Caire

This paper investigates the joint uplink scheduling and power control problem in a coordinated multicell wireless network, where at most one single-antenna user is allowed to access the single-antenna base station in each cell simultaneously. The resulting weighted sum-rate (WSR)…
