Development of Multi-Channel MIMO SC-FDE Modem for 700-Mbps-class Immersive Video Transmission using Millimeter-Wave Band

We have been conducting research and development on a wireless transmission scheme using the 42-GHz-band in millimeter waves, which enables large-capacity transmission with a wide frequency bandwidth, to realize the wireless transmission required for content production such as 3D and ultra-wide field-of-view video that provides a sense of presence and immersion. This paper reports a prototype modem that implements a multi-channel 2 × 4 MIMO SC-FDE system that is capable of 700-Mbps-class signal transmission and the results of evaluating its basic performance. By comparing the bit error rate characteristics of the AWGN channel between the computer simulation and prototype, it was confirmed that the prototype achieves the desired performance and provides a prospect for realizing 700-Mbps-class immersive video transmission using a 42GHz band multi-channel 2 × 4 MIMO SC-FDE system.
