Motivated by the need for robust and high throughput communication with airborne platforms, a variable rate MIMO scheme that combines the D-BLAST architecture with per antenna spreading was proposed. This paper is focused on the experimental study of this approach. We developed a software defined radio implementation of the variable rate MIMO system based on GNU Radio. Over the air transmission and...
In this paper, we propose two novel HARQ schemes based on dual-stream joint beamforming for long term evolution (LTE) advanced system. As one of the most competitive techniques, dual-stream beamforming can achieve multiplexing gain together with beamforming gain. In this paper, algorithm for beamforming vectors is investigated and two novel HARQ schemes are proposed on this basis to further increase...
