Hardware Design of Transmitter and Receiver for High Quality Video Transmission

摘要

The demand for high-resolution wireless video transmission technology is expected to increase greatly as the video resolution increases, and as the Wi-Fi devices spread. Wireless transmission of high-resolution video requires high throughput, therefore it is necessary to use a multiple-input multiple-output (MIMO) system. In this paper, we propose an evaluation platform for video transmission method based on joint source-channel coding (JSCC) that suppresses the degradation of received video by combining source coding and precoding, and efficient hardware software co-design for implementing it on hardware such as field-programmable gate array (FPGA) board. As a result of simulation, beamforming based on eigenbeam-space division multiplexing (E-SDM), one of the precoding method, is performed and the effectiveness of the proposed method has been confirmed.
