Abstract of the Presentation:

From frequency selective surfaces (FSS) to electromagnetic band-gap (EBG) ground planes, from impedance boundaries to Huygens metasurfaces, novel electromagnetic surfaces have been emerging in both microwaves and optics. Many intriguing phenomena occur on these surfaces, and novel devices and applications have been proposed accordingly, which have created an exciting paradigm in electromagnetics, so called “surface electromagnetics”. This seminar will review the development of electromagnetic surfaces, as well as the state-of-the art concepts and designs. Detailed presentations will be provided on their unique electromagnetic features. Furthermore, a wealth of practical examples will be presented to illustrate promising applications of the surface electromagnetics in microwaves and optics.

ABSTRACT:

Non-orthogonal multiple access (NOMA) is a spectrally efficient multiple access technique, which has the potential to meet the rapidly increasing traffic demand of the fifth generation (5G) wireless networks. With NOMA, multiple users can be simultaneously served by the same base station via exploiting the power domain in addition to the time and frequency domains. However, by sharing the frequency channel and transmit power among the paired NOMA users, NOMA may not always achieve better performance than orthogonal multiple access (OMA). In this talk, the basic idea of NOMA transmission is discussed. For downlink NOMA transmission with dynamic traffic arrival for spatially random users, two variants of NOMA schemes, namely opportunistic NOMA and cooperative NOMA with full-duplex relaying, are proposed to enhance the stable throughput region, which is characterized by using tools from queuing theory and stochastic geometry.  Results show that the sum rates of the proposed NOMA schemes over OMA are higher when users having more diverse target data rates are paired.

TITLE: Novel Chirp Spread Spectrum Methods for Low-Power Wide-Area Networks

SPEAKER: Dr. Ha Nguyen

ABSTRACT:

Low-power wide-area networks (LPWANs) have recently emerged as a promising communication technology for the Internet of Things (IoT). LPWANs are designed to achieve large coverage ranges, extend battery lifetimes of end-devices, and reduce the operational cost of traditional cellular networks. By exploiting the unlicensed, industrial, scientific, and medical (ISM) frequency band and transmitting small packets at low data rates, these networks can be operated with very low reception sensitivities. The long-range and low-power properties of LPWANs make these networks an interesting candidate for smart sensing technology in civil infrastructures as well as in industrial applications.

This talk first introduces the chirp spread spectrum (CSS) technique used in low-power wide-area networks known as LoRa. Then it presents novel approaches to modulate and demodulate LoRa signals with high implementation efficiency, flexibility and excellent performance. The last part of the talk explains a method to exploit the phase information of CSS signals to encode extra information bits, leading to throughput improvement of the conventional CSS system.
