TR-OFDM-MIMO platform developed for intra-spacecraft wireless communications

A software defined radio based time reversal orthogonal frequency division multiplexing multiple-input multiple-output (TR-OFDM-MIMO) platform has been developed at University of Electronic Science and Technology of China (UESTC) for the purpose of intra-spacecraft wireless communication applications. After describing the principle and basic architecture of the TR-OFDM-MIMO platform, an experimental demonstration of wireless video transmission in a closed metal box is presented. The results show that the developed platform works reliably inside the richly scattering metal box, indicating a promising solution to the mission of cable-free data transfer inside the closed space capsules.
