Signal Transmission and Detection Theory

Key Features

This lecture is alternatively taught in the every other year with Professor Masaaki Katayama. When my turn comes to take charge of the lecture, I teach WSN.

Theory of WSN covers, sensing theory, communication and networks, distributed sensing theory, signal processing, control theory, system theory and more. In this lecture, I mainly focus on signal processing and detection theory, communication and network theory. I try to organize to teach only the essence of those theories and try not to give every detail. Students will be asked to read the original papers of WSN for deeper understanding and write reports about them. I also present brief survey of current research trend of WSN to draw students' attentions.

Course Aims

  1. To introduce the fundamentals of WSN and students can explain feature, technical problem and the trend of WSN.
  2. To introduce the distributed detection and students can explain it.
  3. To introduce the capacity of WSN and students can explain it.
  4. To introduce the protocol of WSN and students can explain it.

It is highly recommended that you take the courses "Transmission System Engineering", "Information & Communications Engineering 1", "Information & Communications Engineering 2", and "Information & Communications Engineering 3" beforehand.
