Description: 摘要: 在以前的数字蜂窝系统中，往往采用FSK、ASK、PSK等调制方式。随着数字蜂窝系统的发展，对调制和数字蜂窝系统的技术要求越来越高, 许多优秀的调制技术应运而生，其中PI/4-QPSK技术是无线通信中比较突出的一种二进制调制方法-Abstract: In previous digital cellular systems, often using FSK, ASK, PSK, such as modulation. With the development of digital cellular systems, the digital cellular system modulation and the technical requirements of increasingly high, and many excellent modulation technique came into being, PI/4-QPSK wireless communications technology is more prominent in a binary modulation methods Platform: |

Description: FSK（Frequency-shift keying）- 频移键控是利用载波的频率变化来传递数字信息。它是利用基带数字信号离散取值特点去键控载波频率以传递信息的一种数字调制技术。FSK（Frequency-shift keying）是信息传输中使用得较早的一种调制方式-FSK (Frequency-shift keying)- Frequency shift keying is the use of the carrier frequency to transmit digital information. It is the use of discrete values of the baseband digital signal to the keying features of the carrier frequency to transmit information in a digital modulation technique. FSK (Frequency-shift keying) is used in transmission of information obtained earlier a modulation Platform: |
