de-spread meaning in Chinese
解扩散
Examples
- De - spreading technique of one m - ary orthogonal spread spectrum system
一种多进制正交扩频方案的解扩技术研究 - A de - spread spectrum method of ds - cdma based on time - frequency two dimension spread spectrum
的一种时频二维联合解扩方法 - The output components of the de - spreading correlator are analyzed and the expressions for the pf and pd of the step acquisition are given under the condition of additive white gauss noise
并在接收端噪声为加性白噪声情况下，对解扩相关器输出成分作了详细的分析，推导出了步进搜索时的虚警概率和检测概率的公式。 - This dissertation proposes to adopt poly - phase filtering channelized receiver to receive the special multi - carrier ds - cdma signal , which is studied by this dissertation , and use digital matched filter to de - spread signal
在此基础上提出采用多相滤波器组信道化接收机来接收本文研究的多载波扩频通信信号，并使用数字匹配滤波器进行解扩。 - The data recovery at the receiver requires the spreading codes . in sess system , the receiver doesn ’ t know which spreading code will be used , so first it must de - spread the received signal correctly to regenerate the spreading code
自编码扩频系统的扩频序列是接收端事先未知的,不能用事先设计的本地扩频序列产生器产生,需要由恢复的数据获得。
