Research Overview

Fundamental and applied research into digital signal processing hardware and software.

Research Subjects

  • 1. Optimal design of digital circuits and high-frequency circuits with optimization algorithms.
  • 2. Hardware algorithms for combinatorial optimization.
  • 3. Applications of digital signal processing to financial markets.
  • 4. Analysis and design of microwave circuits based on electromagnetic field theory.
  • 5. Development of microwave circuit and EM field simulators.
  • 6. Wireless power transmission technology for high-frequency circuits.

Introduction:

Our research interests focus on digital circuits and high frequency circuits. We are also developing the following application systems.

  • 1. Using intelligent optimization algorithms for the optimal design of digital circuits to produce digital circuits for hardware and software automatically without professional design skills.
  • 2. Analyzing and designing microwave circuits and millimeter wave circuits for information and communication technologies and wireless power transmission technologies by using 3D electromagnetic field theory.
  • 3. Modeling time-series data of stock and foreign exchange markets by using digital signal processing techniques. This work can be applied to predicting financial markets and producing artificial financial time-series data.
