报告内容简介：Topic: Intuition in Applications of Network Coding
Network coding (NC) brings a paradigm shift in the data transport mode from the traditional store-and-forward. The linear-algebraic theory of NC structures data units as a finite field, and the fundamental theorem guarantees the best possible throughput. Linearity makes the hardware/software implementation feasibly fast for practical applications, including wireless communications, redundant storage, P2P content delivery, IC layout, security, optical communications, sensor networks, etc. All these applications are under different contexts. Luckily the Butterfly Network provides an example that is comprehensible to people in all walks of life and, at the same time, is generalizable into elegant mathematics. The wide applicability of NC has generated interest in multi-disciplinary research among computer science, information/coding theory, matrix theory, networking, operations research, ASIC, and switching. Since 2003, the NC literature has grown explosively to the size of about 10,000.

报告内容简介：Topic: Signal Identification for Spectrum Sharing
With the advent of the mobile internet and internet of things, the spectrum scarcity and the wireless network security has become a main challenge of the fifth generation mobile communication system and its beyond due to the explosive growth of devices and traffic. In this talk, we consider the techniques including the modulation classification and specific emitter identification, and investigates the intelligent spectrum access and sharing schemes and secure transmission strategies. Existing literature on signal identification focuses on the ideal scenarios, which lacks of the investigations on realistic conditions such as the complicated channels, multiuser and non-ideal receptions. We analyze and model the mechanisms of the identification features, and further propose the feature extraction and classification algorithms with high accuracy and robustness, by using the machine learning.

报告内容简介：循环移位网络编码
We study a class of linear network coding (LNC) schemes, called circular-shift LNC, whose encoding operations at intermediate nodes consist of only circular-shifts and bit-wise addition (XOR). Departing from existing literature, we systematically formulate circular-shift LNC as a special type of vector LNC, where the local encoding kernels consist of cyclic permutation matrices. Under this new framework, we shall briefly introduce its intrinsic connection of conventional scalar LNC and how to efficiently construct the circular-shift LNC schemes with low encoding and decoding complexities.
