数据符号
资料符号
Examples
- Planar double - enveloping worm gearing geometrical data symbols
平面二次包络环面蜗杆传动几何要素代号 - End - data symbol
数据终端符号 - When ccc are used for spreading codes , multiple access interference ( mai ) is zero theoretically even under asynchronous transmission . if cc / ccc are used for spreading codes , one data symbol could be transmitted during one - chip duration
若采用互补码作为扩频码，理论上而言，不管在同步模式还是异步模式下，都不存在多址干扰；又可用特殊的调制方式做到在1个码片的时间内传输一个数据符号。 - And it presents an estimation method for frequency difference by means of data synchronization selecting the time window of afc frequency difference estimation hi order to solve the problem that data symbol transition induces an enormous error of frequency difference estimation
针对afc频差估计中数据突变引起频差估计较大误差的问题，提出了利用数据符号同步对afc频差估计时间窗口选择的afc频差估计方法。 - With mc - cdma , each data modulated chip of the user specific spreading code is mapped onto a separate subcarrier after spreading and scrambling , so that the chips of the spreading code and , hence , the data symbol is transmitted in parallel on multiple subcarriers
Mc - cdma是将多载波技术应用于cdma中，兼具cdma和ofdm这两种技术的特点。在mc - cdma中，用户的信息符号先经过扩频、加扰，再将扩频序列的码片并行地在多个子载波上传输。
