Introduction

(1) Research on One-dimensional (1-D) and Two dimensional (2-D) Digital Signal Processing: Theory and Design of 1-D and 2-D FIR and IIR digital filters and filter banks with continuous filter coefficients or discrete filter coefficients. For many communication and signal processing systems, quadrature mirror filter (QMF) banks have been widely used to achieve the goals of subband coding and short-time spectral analysis. In these applications, a QMF bank is employed to decompose a signal into subbands and the subband signals in the analysis system are decimated by an integer equal to the number of subbands. We have studied and developed theory and design of 1-D, 2-D Filters, Filter Banks, and Wavelet Filter Banks with linear phase or low group delay response for Applications in Audio, Image, and Video Signal Processing.

(2) Research on 1-D and 2-D adaptive array signal processing: Theory and Robust techniques for 1-D and 2-D adaptive array beamforming and bearing estimation in the presence of coherence signal sources, array sensor position errors, near field sources, and steering angle error, etc. One of the most important problems in a multiuser asynchronous environment is the inter-user interference, which can degrade the performance quite severely. This is the case also in a practical Code-Division Multiple Access (CDMA) system, because the varying delays of different users induce non-orthogonal codes. The base stations in mobile communication systems have long been using spatial diversity for combating fading due to the severe multipath. However, using an antenna array of several elements introduces extra degrees of freedom, which can be used to obtain higher selectivity. An adaptive receiving array can be steered in the direction of one user at a time, while simultaneously nulling interference from other users, much in the same way as the beamforming techniques. Recently, we also consider the research on OFDMA wireless communication systems. Theory and Techniques have been studied and developed for the adaptive processing of array signals in Smart Antennas with Applications in Wireless, Mobile Communications, and Anti-jamming Communications.

(3) Based on the achievements from (I) and (II), we have been conducting some more advanced researches including the explorations of theories and applications in the areas of multiple-input multiple-output (MIMO) wireless communication systems and MIMO radar systems for the next generation MIMO wireless communications.

Introduction

Google and IBM have built their own small-scale quantum computers, which leads to a brand-new quantum era. It becomes a pressing matter to study how to harness the power of quantum computers to invent quantum information technology and thus to revolutionize Taiwan's Information and Communications Technology. Prof. Cheng proposes to apply his research expertise of quantum information processing techniques to investigate three major quantum information technologies - (i) quantum communication network, (ii) quantum circuits learning, (iii) quantum encryption, and (iv) quantum-enhanced artificial intelligence. Firstly, the study of quantum communication network involves designing multiple-terminal quantum information transmissions and receptions. This can be applied to simulate global operations in quantum computing. Secondly, quantum circuits learning aims to identify the unknown quantum circuits by using a series of quantum states as training samples. This will lead to applications of quantum circuits verification and testing. Thirdly, the study of quantum encryption can facilitate our national security. Fourthly, quantum-enhanced artificial intelligence harnesses the advantage of quantum resources to improve the efficiency and performance of machine learning and artificial intelligence tasks. Prof. Cheng proposes to employ this technology to integrate and enhance the development of artificial intelligence in the College of Electrical Engineering and Computer Science at the National Taiwan University (NTU) and the industries in Taiwan. The ultimate goal is to accomplish quantum information technology in the near-term future, and integrate the research and development between NTU, Ministry of Science and Technology (MoST), and the related industry-academia partnerships.
