数据符号 meaning in English
data symbol
Examples
- International gear notation . symbols for geometrical data
齿轮国际符号表示法.几何数据符号 - International gear notation - symbols for geometrical data
国际齿轮符号表示法.几何数据符号 - 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。 - The 3rd generation ( 3g ) mobile communications system and part of the 2nd generation ( 2g ) mobile communications use pn sequences or walsh codes as spread codes , and their system capacities are limited by the multiple access interference ( mai ) from asynchronous transmitted signals
采用pn序列和walsh码进行直序列扩频的第三代和部分第二代cdma移动通信系统，其容量受到异步传输时多址干扰的限制，其数据率因在n个码片的时间内只能传输一个数据符号而受限。
