radio-frequency channel的意思|示意

Traditionally, DSP only concerns in source coding as well as channel coding, but today, it begins to set foot in radio frequency modulation field.

信源编码，信道编码是DSP在通信信号处理中的传统经典应用，而如今DSP已深入射频调制部分。

The AGC technology in the radio frequency channel is also studied.

研究了射频信道中的自动增益控制技术。

RFID (Radio Frequency identification) is one of the identification technologies which can realize intercommunication by using wirelesss channel.

射频识别技术是利用无线信道实现双向通信的一种识别技术。

However, for the wireless mobile communication systems, the radio channel is frequency selective and time-varying.

对于无线通信系统，无线信道不仅是频率选择性的，而且是时变的。

Network channel is base on frequency hopping and spectrum spread radio stations.

网络信道基于跳频和扩频超短波电台。

But radio frequency (rf) front-end imperfections can lead to the loss of channel reciprocity, which will invalidate the advantage of TDD systems.

但是射频器件的非理想特性将导致信道互易性的丧失，使TDD系统的优势无法发挥。
