Wide-Beam Array Antenna Power Gain Maximization via ADMM Framework

no code implementations21 Apr 2021 Shiwen Lei, Jing Tian, Zhipeng Lin, Haoquan Hu, Bo Chen, Wei Yang, Pu Tang, Xiangdong Qiu

This paper proposes two algorithms to maximize the minimum array power gain in a wide-beam mainlobe by solving the power gain pattern synthesis (PGPS) problem with and without sidelobe constraints.

Tensor-based Multi-dimensional Wideband Channel Estimation for mmWave Hybrid Cylindrical Arrays

no code implementations10 Sep 2020 Zhipeng Lin, Tiejun Lv, Wei Ni, J. Andrew Zhang, Ren Ping Liu

Channel estimation is challenging for hybrid millimeter wave (mmWave) large-scale antenna arrays which are promising in 5G/B5G applications.

Complex ResNet Aided DoA Estimation for Near-Field MIMO Systems

no code implementations21 Jul 2020 Yashuai Cao, Tiejun Lv, Zhipeng Lin, Pingmu Huang, Fuhong Lin

By converting it into a regression task, a novel DoA estimation framework based on complex-valued deep learning (CVDL) is proposed for the near-field region in short-range MIMO communication systems.
