Dual band wireless transmission over 75-150GHz millimeter wave carriers using frequency-locked laser pairs

no code implementations27 Oct 2023 Zichuan Zhou, Amany Kassem, James Seddon, Eric Sillekens, Izzat Darwazeh, Polina Bayvel, Zhixin Liu

We generate and transmit 75-GHz-bandwidth OFDM signals over the air using three mutually frequency-locked lasers, achieving minimal frequency gap between the wireless W and D bands using optical-assisted approaches, resulting in 173. 5 Gb/s detected capacity.

Controllability of networked multiagent systems based on linearized Turing's model

no code implementations26 Oct 2023 TianHao Li, Ruichang Zhang, Zhixin Liu, Zhuo Zou, Xiaoming Hu

Under mild conditions on the parameters of the linearized Turing's model, we prove the equivalence between controllability of the linearized Turing's model and controllability of a Laplace dynamic system with agents of first order dynamics.

Stability of FFLS-based diffusion adaptive filter under a cooperative excitation condition

Steady state behavior of the free recall dynamics of working memory

no code implementations22 Sep 2022 TianHao Li, Zhixin Liu, Lizheng Liu, Xiaoming Hu

Finally, we give a sufficient condition under which this model has a globally asymptotically stable equilibrium with synchronized minicolumn states in each hypercolumn, which implies that in this case recalling is impossible.

Convergence of the Distributed SG Algorithm Under Cooperative Excitation Condition

no code implementations5 Mar 2022 Die Gan, Zhixin Liu

In this paper, a distributed stochastic gradient (SG) algorithm is proposed where the estimators are aimed to collectively estimate an unknown time-invariant parameter from a set of noisy measurements obtained by distributed sensors.
