Joint Beamforming Design and Stream Allocation for Non-Coherent Joint Transmission in Cell-Free MIMO Networks

no code implementations28 Feb 2024 Xi Wang, Xiaotong Zhao, Juncheng Wang, You Li, Qingjiang Shi

We then propose a joint beamforming and linear stream allocation algorithm, termed as RWMMSE-LSA, which yields closed-form updates with linear stream allocation complexity and is guaranteed to converge to the stationary points of the original joint optimization problem.

Decentralized Equalization for Massive MIMO Systems With Colored Noise Samples

no code implementations22 May 2023 Xiaotong Zhao, Mian Li, Bo wang, Enbin Song, Tsung-Hui Chang, Qingjiang Shi

However, current detection methods tailored to DBP only consider ideal white Gaussian noise scenarios, while in practice, the noise is often colored due to interference from neighboring cells.

PointTAD: Multi-Label Temporal Action Detection with Learnable Query Points

1 code implementation20 Oct 2022 Jing Tan, Xiaotong Zhao, Xintian Shi, Bin Kang, LiMin Wang

Traditional temporal action detection (TAD) usually handles untrimmed videos with small number of action instances from a single label (e. g., ActivityNet, THUMOS).

Rethinking WMMSE: Can Its Complexity Scale Linearly With the Number of BS Antennas?

1 code implementation12 May 2022 Xiaotong Zhao, Siyuan Lu, Qingjiang Shi, Zhi-Quan Luo

Precoding design for maximizing weighted sum-rate (WSR) is a fundamental problem for downlink of massive multi-user multiple-input multiple-output (MU-MIMO) systems.

Decentralized Linear MMSE Equalizer Under Colored Noise for Massive MIMO Systems

no code implementations23 Jun 2021 Xiaotong Zhao, Xin Guan, Mian Li, Qingjiang Shi

Conventional uplink equalization in massive MIMO systems relies on a centralized baseband processing architecture.
