PN sequence 例句

英汉例句

  • In direct sequence spread spectrum communication system, enemy is assumed to detect whole PN sequence chip by chip and a modulated retransmitted interference is created.

    在直接序列扩频通信系统中，假设敌方能够逐个比特地检测到整个PN序列，并产生一个调制的转发干扰。

  • Simulations show that the scheme gives a signal-to-noise ratio (SNR) improvement of about 0.4 dB over a frequency-selective fading channel compared with PN sequence padding.

    仿真表明，在频率选择性信道下误符号率较PN序列填充方案有0.4dB左右的性能改善。

  • Furthermore, this system lowers the data rate of each carrier branch, so it is easier to make PN sequence synchronized.

    由于该系统降低了每个子载波上的数据速率，扩频序列更容易同步。

  • The first kind of the frame synchronization algorithm employs the correlation of the long PN sequence and the redundancy of the guard interval to produce the synchronization signal.

    第一种帧同步算法直接利用了一个长PN序列产生相关并融合保护间隔的冗余特性获得同步信号。

  • In the system of spread-spectrum communication, the essential point of demodulating information is to ensure the synchronism of local PN sequence and PN sequence of received signals.

    扩频通信系统中，保证本地产生的PN序列与接收信号中的PN序列完全同步，是正确解调信息的关键点。
