Abstract
In order to support high-definition video transmission, an implementation of video transmission system based on Long Term Evolution is designed. This system is developed on Xilinx Virtex-6 FPGA ML605 Evaluation Board. The paper elaborates the features of baseband link designed in Xilinx ISE and protocol stack designed in Xilinx SDK, and introduces the process of setting up hardware and software platform in Xilinx XPS. According to test, this system consumes less hardware resource and is able to transmit bidirectional video clearly and stably.
Highlights
The Long Term Evolution (LTE) is standardized by the 3GPP, as the successor of the Universal Mobile Telecommunication System (UMTS), in order to ensure a high speed data transmission with mobility for mobile communication [1]
LTE improves on the 3GPP air interface, and applies Orthogonal Frequency Division Multiplexing (OFDM) and Multiple Input Multiple Output (MIMO) to improve the performance of wireless system
We propose a bidirectional video transmission system based on LTE
Summary
The Long Term Evolution (LTE) is standardized by the 3GPP, as the successor of the Universal Mobile Telecommunication System (UMTS), in order to ensure a high speed data transmission with mobility for mobile communication [1]. With the increase of the pace of modern life, people are eager for high-speed wireless access services at all times and places. Reference [6] mentions the implementation of hardware platform for LTE baseband link, but doesn’t refer to the design of protocol stack. Reference [7] implements data transmission on system layer, but doesn’t mention about the development of hardware platform. We set up system platform on Virtex-6 FPGA in Xilinx XPS environment to support protocol stack and baseband link. Protocol stack is designed in Xilinx SDK environment to conduct data transmission between digital video server (DVS) and baseband link.
