Joint Design of ISAC Waveform under PAPR Constraints

no code implementations20 Nov 2023 Yating Chen, Cai Wen, Yan Huang, Le Liang, Jie Li, HUI ZHANG, Wei Hong

In this paper, we formulate the precoding problem of integrated sensing and communication (ISAC) waveform as a non-convex quadratically constrainted quadratic program (QCQP), in which the weighted sum of communication multi-user interference (MUI) and the gap between dual-use waveform and ideal radar waveform is minimized with peak-to-average power ratio (PAPR) constraints.

Gradient-Based Markov Chain Monte Carlo for MIMO Detection

no code implementations12 Aug 2023 Xingyu Zhou, Le Liang, Jing Zhang, Chao-Kai Wen, Shi Jin

However, optimal MIMO detection is associated with a complexity that grows exponentially with the MIMO dimensions and quickly becomes impractical.

SAFARI: Sparsity enabled Federated Learning with Limited and Unreliable Communications

no code implementations5 Apr 2022 Yuzhu Mao, Zihao Zhao, Meilin Yang, Le Liang, Yang Liu, Wenbo Ding, Tian Lan, Xiao-Ping Zhang

It is demonstrated that SAFARI under unreliable communications is guaranteed to converge at the same rate as the standard FedAvg with perfect communications.

Deep Learning based Wireless Resource Allocation with Application to Vehicular Networks

no code implementations7 Jul 2019 Le Liang, Hao Ye, Guanding Yu, Geoffrey Ye Li

The traditional wisdom is to explicitly formulate resource allocation as an optimization problem and then exploit mathematical programming to solve the problem to a certain level of optimality.

Spectrum Sharing in Vehicular Networks Based on Multi-Agent Reinforcement Learning

1 code implementation8 May 2019 Le Liang, Hao Ye, Geoffrey Ye Li

This paper investigates the spectrum sharing problem in vehicular networks based on multi-agent reinforcement learning, where multiple vehicle-to-vehicle (V2V) links reuse the frequency spectrum preoccupied by vehicle-to-infrastructure (V2I) links.

Deep Learning based End-to-End Wireless Communication Systems with Conditional GAN as Unknown Channel

no code implementations6 Mar 2019 Hao Ye, Le Liang, Geoffrey Ye Li, Biing-Hwang Fred Juang

We propose to use a conditional generative adversarial net (GAN) to represent channel effects and to bridge the transmitter DNN and the receiver DNN so that the gradient of the transmitter DNN can be back-propagated from the receiver DNN.

Toward Intelligent Vehicular Networks: A Machine Learning Framework

no code implementations1 Apr 2018 Le Liang, Hao Ye, Geoffrey Ye Li

As wireless networks evolve towards high mobility and providing better support for connected vehicles, a number of new challenges arise due to the resulting high dynamics in vehicular environments and thus motive rethinking of traditional wireless design methodologies.
