Speech Title: Microwave photonic signal processing and sensing

Abstract: Photonic signal processing offers the prospect of overcoming a range of challenging problems in the processing of high-speed signals. Its intrinsic advantages of high time-bandwidth product and immunity to electromagnetic interference (EMI) have led to diverse applications. Photonic signal processing leverages the advantages of the optical domain to benefit from the wide bandwidth, low loss, and natural EMI immunity that photonics offers. Next generation global telecommunication platforms and emerging applications in radar, communications and sensing will require entirely new technologies to address the current limitations of electronics for massive capacity and connectivity. Microwave photonics, which merges the worlds of RF and photonics, shows strong potential as a key enabling technology to obtain new paradigms in the processing of high speed signals that can overcome inherent electronic limitations. In addition, the growth of silicon photonics allows integration together with CMOS electronics, to obtain future signal processing systems that can implement high bandwidth, fast and complex functionalities. Recent advances in microwave photonic signal processing are presented. These includes versatile beamforming and beam steering systems for phased array antennas, single bandpass microwave photonic filters, photonic-assisted scanning receivers for microwave frequency measurement, and microwave photonic sensing systems. These microwave photonic processors provide new capabilities for the realisation of high-performance signal processing and sensing.

Speech Title: Transforms of Multiwavelet and Multiwavelet Packet with Application in Identifying Heroin Addict Pulse Signals

Abstract: It is well known that the multiwavelets are a natural generalization of the scalar wavelets and can be viewed as vector-valued wavelets which have several advantages in comparison to scalar wavelets. Correspondingly, the multiwavelet transforms can provide more adaptive to satisfy the requirements of a variety of signal analysis. On the other hand, the multiwavelet transforms have also a fast computational structure for multiresolution analysis, which can be viewed as a generalization of the fast algorithm of Mallat’s multiresolution analysis for the case of scalar discrete wavelet transforms. However, while using the Mallat’s multiresolution analysis method to realize a multiwavelet transform, only the decomposed lowpass component at a decomposition stage is further decomposed, and the highpass component is left unchanging further. Therefore, the multiwavelet transforms can not supply finer time-frequency localized information for high frequency component obtained at every decomposition stage. Naturally, the concept of wavelet packet transforms was introduced into the multiwavelet transforms, which led to the so-called multiwavelet packet transforms. Thus, both the lowpass and highpass components at any decomposition stage can be further decomposed, with the result that any finer degree of the time-frequency localization can be obtained. It is really a great interesting to explore the effectiveness of these two modern signal processing techniques in identifying heroin addict pulse signals. In the research, the transforms of multiwavelet and multiwavelet packet are, respectively, used to decompose pulse signals collected from 15 heroin addicts and 15 healthy normal subjects. Combining entropy techniques in the feature extraction, the feature vectors have good distributive properties in feature plane. To obtain a good generalization for classification of two classes of pulse signals, the vector support machine is introduced. It is expected to receive good research results.
