Lab orientation/tour for 3rd-year undergraduate students, 2023

We will conduct a laboratory orientation for third-year undergraduate students as per the following schedule:

  • Location: 11-12, IST Building 11th floor
  • Date and Time: Oct 27 (Fri) at 13:00-, 14:00-, 15:00-
    (Note: Although this is the last day of the lab tour period. Please try to join us at an earlier time if possible. We may not conduct the session after 15:00 if there are no participants.)

Visits (tours) to the lab are also possible. The available time slots are as follows:

  • Location: ICN Lab., IST Building 11th floor
  • Date and Time: Students will definitely be available during the following hours.
    (For Wednesdays and Thursdays, please refrain from visiting before the end of the experiment; School of Engineering Timetable)

Hokuyukai Alma Mater Networking Event 2023

Mr. Kyotaro Kunii made a poster presentation entitled “Investigating the Impact of LDPC Codes on LoRa Modulation Communication Performance” at Hokuyukai Alma Mater Networking Event (in Japanese).

IEICE Society Conference, September 12-15, 2023, at Nagoya University

From September 12th to 15th, 2023, Mr. Mochizuki, a Master’s second-year student in our laboratory, presented his research findings at the IEICE Society Conference held at Nagoya University. It’s worth noting that this was the first full in-person event since the Society Conference was last held at Osaka University in 2019. Normally, IEICE conferences feature a general reception desk where attendees can exchange their registration slips for a participant’s kit. However, this time, no such general reception desk was set up. Instead, participants were required to print their own name tags and bring them to the venue. Name tag holders were then distributed in each session room for attendees to use. Additionally, a conference app was introduced, which allowed attendees to access papers and other relevant information.
