Mimo Experiment System Of Data Acquisition And Interface Technology

With the development of mobile communication, the demands for the limited frequency resource are booming. To develop highly efficient coding, modulation and signal processing technologies is becoming the most necessary measure to meet these demands. Multiple-Input & Multiple-Output intelligent antenna technique, as the key technique of the fourth generation mobile communication, becomes the important research topic, and this enormously increases the wireless communication system capacity as well as diversity advantage and coding gain without additional system bandwidth and transmitting power. We need to complete a set of MIMO experiment system, include the related software,hardware and simulation platform. This is the unique way that we can acquire the true MIMO correspondence data. In the paper, we first look forward to the development of the modern telecommunication and the related hardware platform of our MIMO experiment system is introduced. For the sampling of baseband signals, then the principle and the application of AD9288 are discussed. Based on FPGA(field programmable gate array), in the third chapter a design method of SDRAM controller with EPP interface to computer is proposed . Large-capacity data access is implemented at high speed by the USB(universal serial bus)2.0 circuit. The application of CY7C68013 is recommended detailed in the forth chapter. At last, we validate the usefulness of the experiment system and Prospect our future work.
