Speech Title: Timeliness Challenges for 6G wireless Networks Toward Metaverse
Abstract: Although Metaverse is just a concept, it really bring more imagination in the industries and academics. At the same time, 6G wireless networks is also proposed, which bring some new features, especially AI computation and inference. In this case, one can easily think to combine these two hot points into one and find some new things in the world, to change our daily life and promote the happiness index. In this talk, we mainly focus on the implementation timeliness. If the promising scenarios is coming, what techniques we need to prepare in 6G wireless networks. We first introduce the Meatverse concept and its potential applications in our daily life and then present its challenge requirements for communication technologies, especially, on the implementation timeliness. Later on, we analyse the existing status for wireless networks from multiple layers and point out the possible solutions to the existing problems and their corresponding new research directions. Finally, we give a short summary to show what we need to do in next step.

Speech Title: Channel Estimation and Diversity Reception for RIS-Empowered Broadband Wireless Systems
Abstract: Channel estimation is a challenging problem for reconfigurable intelligent surface (RIS) empowered wireless communications, especially for broadband channels. In this talk, a cyclic-prefixed single-carrier (CPSC) transmission scheme with PSK signaling for this purpose is first introduced. We will see that different cyclically delayed versions of the incident signal can be created by wisely configuring the RIS according to the transmitted PSK symbols. Based on this, a practical and efficient channel estimator can be easily developed and multipath diversity can be harvested. By resorting to the concept of index modulation (IM), this talk will then introduce how to extend CPSC-RIS for improved spectral efficiency. Finally, BER results will be shown to verify the superiority of the presented scheme over the orthogonal frequency division multiplexing (OFDM) solution.

Speech Title: Binary Sparse Signal Recovery with Binary Matching Pursuit
Abstract: In numerous applications from communications and signal processing, we often need to acquire a $K$-sparse binary signal from sparse noisy linear measurements.
In this talk, we first develop an algorithm called Binary Matching Pursuit (BMP) to recover the $K$-sparse binary signal. According to whether the residual vector is explicitly formed or not at each iteration, we develop two implementations of BMP which are respectively called explicit BMP and implicit BMP. We then analyze their complexities and show that, compared to the Batch-OMP, which is the fastest implementation of OMP, the improvements of the explicit and implicit BMP}algorithms are respectively $n/(2K)$ and $K$ times when some quantities are pre-computed. Finally, we provide sharp sufficient conditions of stable recovery of the support of the sparse signal using mutual coherence and restricted isometry property of the sensing matrix.

Speech Title: Real-time estimation of global states on software-defined random opportunistic networks
Abstract: This talk proposes a new idea to apply the thoughts of software-defined networks into random opportunistic networks. To realize the software-defined random opportunistic networks gives rise to a critical issue how a controller node to capture the knowledge of real-time global network states. Nevertheless, the existing algorithms that estimate the global states of ad hoc networks are unable to cognize and dynamically compute the real-time global states, being with overloaded messages, in spite of their relatively lower computational complexity normally. To solve this problem, this talk proposes a novel idea to replace message exchanges between nodes by computing the structural properties of networks, with the theory of network eigen-spectral reconstruction to estimate the real-time global states of random opportunistic networks. Some research topics got involved such as eigenvalue filtering are also investigated. The research results expand the theories of network reconstruction and distributed estimation convergence etc., break through the technical bottleneck of real-time computation for dynamic global state information, clear the critical technical obstacles for the implementation of software-defined network thoughts, and break a new path to implement both green and secure communications.
