Abstract
We are conducting research on the next-generation 1.2-GHz/2.3-GHz-band mobile field pick-up unit(FPU) system that can wirelessly transmit Super Hi-Vision video materials. We have so far proposed the 4×4 TDD-SVD-MIMO system that adaptively controls transmit parameters depending on channel conditions, and evaluated the transmission performance by both computer simulation and indoor measurements that used our prototype system. In this report, we describe an outdoor experiment to test the prototype system in the urban area around NHK technical laboratories. Our results showed that the prototype system could achieve the transmission rate of more than 100 Mbps in mobile environments.
