Wireless communication is becoming a main part of multimedia communication services and the video coding and transmission are turning into the new research focus. Video service is featured with large data quantity and high requirement for bit error rate, wireless channel is liable to error and restricted bandwidth, and multipath effect may result in slow fading and fast fading, which causes much higher bit error rate than that of wired environment. Therefore, when video communication is applied in wireless communication, there is the need to coordinate the relationship between power consumption, error tolerance and compression efficiency .

无线通信正在成为多媒体通信业务的一个新的主体,其视频的编码和传输问题也正在形成新的研究热点.由于视频业务数据量大,对误比特率要求高,无线信道又具有易错、时变和带限的特点,且多径现象会导致慢衰落和快衰落,使得信道误比特率要比有线环境大得多.因此视频通信应用到无线通信中时,需协调好功耗、容错能力、压缩效率三者之间的关系.

LAMOST optical fiber orientation system has difficulties of large data quantity (about dozens of G bytes), fast process speed (whole orientation process must be finished in several minutes), and high precision (uncertainty is within 10 μm). Aim at these problems, this paper advances a parallel data acquisition and process system, in which each data acquisition and process system works independently. Double RAM working mode is applied to every CCD unit, the two data buffer works alternatively, so the process time is radically reduced, pre process the large quantity of data acquired by the system to decrease the quantity of valid data. This paper analyzes this data acquisition project in detail.

针对 L AMOST光纤定位系统中球焦面位置测量系统需要处理的数据量大 (约为几十 G)、要求处理速度快 (整个定标时间数分钟 )、精度高 (总不确定度 10 μm以内 )的特点 ,提出了一套并行数据采集与处理方案 ,使各个数据采集处理单元并行独立工作 ;每个 CCD单元采用双 RAM工作方式 ,两块数据缓冲区乒乓工作 ,大大缩短了数据采集处理时间 ,对系统每次采样得到的大量数据进行预处理 ,从而减少有用数据的存储量。本文对本数据采集方案进行了详细的分析。
