相位调制系统 meaning in Chinese

phase modulation system

Chapter 2 treats the design of digital phase modulation system in frequency hopping mode communication
第二章说明了跳频传输模式下数字相位调制系统的设计。
Recently , frequency - hop communication has been widely used in many military wireless communication domain as a secure transmission mode . in frequency - hop transmission , phase modulation system has good performance and high frequency efficiency
跳频传输模式下的数字相位调制系统具有较高的抗噪声性能，且能有效地利用频带，实现数据的高速传输，是一种比较优越的调制方式。
Then , the frequency - hop system is presented . emphasis is placed on the analysis of effect on the phase modulation system which is produced in frequency - hop transmission . at last , we scheme out the fh - mpsk and fh - / 4dqpsk systems according to the frequency - hop communication characteristics
首先介绍了跳频通信的信道特性，然后说明了跳频系统的工作情况，并分析了跳频传输对相位调制系统设计的影响，最后针对跳频通信的特点设计出跳频传输模式下的fh - mpsk和fh - 4dqpsk系统。
