  1. Based on the analysis, we bring up a new way of thinking, after considering the characteristics of the dds design in software radio system platform. we adopt the rom compression technique of dds special chip and other optimizing methods in the design. we still bring up a new modified method, of which the compression ratio is 139. 6 : 1

    在此理論分析礎上,針對在軟體無線平臺中的直接數字頻率合成設計特點,對dds專用晶元進行分析后提出新思,將dds專用晶元中所使用的幅度表技術用於軟體無線平臺中的dds設計,同採用其它輔助方法進行了優化設計,並提出一種新的改進方法,將比提高到139 . 6 : 1 ,很好的改進了軟體無線平臺中直接數字頻率合成的雜散抑制性能。
  2. Time - base pressing circuit

  3. With performance of up to 900 million floating - point operations per second ( mflops ) at a clock rate of 150 mhz, tms320c6711 is fit to tackle with the problem. this thesis made a deep research on the h. 263 standard and the tms320c6711. we propose the plan of the software and the hardware for the realization of the h. 263 protocol which include the structure of the whole program, the c code of the key algorithm of the h. 263, the c code of some subprogram, and the circuit for image processing with the tms320c6711 as the processor. furthermore, we optimize some subprogram in common use to make the coding more quickly. we encode a video sequence with the tms320c6711dsk successfully, even if the compression rate is as high as 100, video effect we get after decoding the code stream is satisfying

    首先系統地研究了h . 263協議編碼器的本演算法,句法,碼流結構和tms320c6711dsk的原理結構以及ccs2 . 0的開發環境;在系統的軟體方面給出了總體流程圖,對于h . 263協議編碼器的某些核心演算法和子程序,給出了部分源代碼,對于dsp的各種代碼優化方法進行了討論,並且對代碼進行優化,從而在提高系統處理速度的同減少代碼大小和內存需求量;硬體方面以tms320c6711為核心處理器,提出了於tms320c6711的圖像處理平臺的硬體實現方案,並給出了原理圖;最後在tms320c6711dsk上成功對視頻數據進行高比( 100倍以上)的編碼,對回傳的結果解碼后得到了令人滿意的效果。
  4. Cobranet audio network technology is the development trend of audio transmission and switching, as the pace of the broadcast digital and networked development is stepping. cobranet audio network technology transmits and distributes real - time and uncompressed digital audio signal. compared with analog, this technology not only transmits high quality audio, but also economize cost. now many broadcasting stations, gymnasiums and meeting places start to make use of this technology to build their network systems. in order to operate and maintain these networks, network managing software aiming at application will be needed

    Cobranet音頻網技術利用快速以太網傳輸和分配實、非的數字音頻信號,在保證傳輸高質量的音頻信號的同,與傳統的模擬方式傳輸音頻信號相比,大大降低了纜布線等成本。目前很多廣播臺、體育中心以及大型會場都開始利用該技術組建自己的音頻網系統,而要運行和維護這個網系統,需要開發專門於cobranet技術的面向應用的網管理軟體。
