Tohoku University Technology: Frequency spectrum reproduction method and receiver: T21-156
Avoid interference between IoT systems and regenerate the signal spectrum.
In recent years, wireless IoT has become widespread, and technologies for real-time spectrum monitoring in frequency bands have been developed to avoid interference between different wireless IoT systems. The signals received by this technology are converted from analog to digital signals by multiple analog-to-digital converters, after which the original spectrum is reproduced. However, due to the lack of tunable filters with low loss and low distortion in current technology, it is not possible to freely set the bandwidth with a single device. As a result, there is a challenge in achieving the Software Defined Radio functionality of receivers. With the present invention, it has become possible to realize spectrum reproduction processing using software. The frequency spectrum reproduction method of this invention does not use a band-pass filter for removing aliasing noise; instead, it samples the received frequency spectrum, generates a vector that combines each frequency spectrum element, and calculates a solution using a priority decision condition algorithm to extract a specified bandwidth. This enables the realization of spectrum reproduction processing using software.

Company information
The revenue generated from technology transfer is reinvested into universities and researchers as new research funding, which is used to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will actively promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by concluding basic technology transfer agreements with the following universities (as of June 1, 2025): - Tohoku University - Hirosaki University - Iwate University - Akita University - Fukushima University - Yamagata University - Tohoku Gakuin University - Iwate Medical University - Fukushima Medical University - Aizu University - Miyagi University - Hokkaido University - Muroran Institute of Technology - Showa Medical University
