radio frequency modulation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。

They do not occur in a decided frequency, but rather through a special modulation, the radio waves identity.

他们通常不发生在确定的频率，而是通过一个特定的调治，来确定无线电波。

AM radio can be sent over larger distances, but the quality of the sound is not as good as a later kind of radio signal processing, called frequency modulation.

调幅广播可以发送更远的距离，但它的声音质量却不及后来一种被称为频率调制的无线电信号处理方式优越。

Therefore, the tuner is essential to the frequency modulation radio.

所以调频收音机中的频率调谐器是至关重要的。

The design scheme of a RFID (Radio Frequency Identification)System is given in this paper. The backscatter modulation technique is used to transmit the data to the reader from a tag.

文中给出射频识别系统的设计方案，系统采用反向散射调制技术完成从电子标签到读写器的数据传输。

This paper gives a simple algorithm of quasi-optimal frequency distribution for mobile radio systems, in which the third-order inter-modulation does not appear. The computation results are given.

本文提出了移动电台无三阶互调的准最优频率分配的简化算法，并给出了计算结果。
