This paper proposes a hardware platform for WCDMA baseband data transmission, which consists of USB3.0 interface, general purposes processor (GPP), and software defined radio (SDR) system. In view of the requirements of WCDMA system, the hardware platform consisting of USB3.0 controller, FPGA and DDRII was selected, which finally realized the high throughput rate and low delay transmission of baseband data of WCDMA system. The experimental results show that in this GPP software defined radio system, the interface speed of USB3.0 can reach 200MBps, and the loopback delay time of the system is about 0.7ms, which can meet the requirements of WCDMA system.

Представлено описание разработанных программных модулей интеллектуальной перестройки рабочих частот для системы когнитивного радио, в которых применяется ранее предложенный алгоритм анализа использования радиочастотного спектра. Также разработаны программные модули для взаимодействия с программно-определяемыми радиосистемами, такими как LimeSDR. Экспериментально показано, что использование алгоритма предсказания занятости частотных каналов позволяет сократить время оперативного сканирования спектра. A description of the developed software modules for intelligent tuning of operating frequencies for the cognitive radio system is presented. These software modules use the previously proposed algorithm of RF spectrum utilization analysis. Also, software modules have been developed for interacting with software-defined radio such as LimeSDR. Experimental studies have shown that the use of an algorithm for predicting the occupancy of frequency channels allows reducing the time of operational scanning of the spectrum.

Acquisition Task

The 3G wireless network video acquisition system based on the DM6446 is designed, which ARM side of DM6446 complete the main control functions of the system, then it calls H.264 video compression algorithm in DSP side of DM6446 through the Codec Engine, which greatly improves the efficiency of the system, and the RTP protocol control data transmission in the CDMA2000 network. The monitoring display terminal gets video resource by accessing the corresponding IP address. The experimental results show that the system designed completes wireless network video acquisition task safety and reliably, and the image is clear, also the video is coherent.
