data modulation rate的意思|示意

The modulation types of data link for UAV are simple, such as BPSK, 2FSK , direct spread spectrum. The transmitted rate and anti-interference performance of them are limited.

目前，无人机数据链系统采用的调制模式都比较简单，如2FSK、BPSK、直接扩频技术等，传输速率与抗干扰能力有限。

OFDM (Orthogonal Frequency Division Multiplexing) is a new modulation technology, it is suitable to high-data-rate transmission in the wireless transfer channel with multi-path transmission.

正交频分复用(OFDM)是一种新型调制技术，特别适合在多径传播的无线移动信道中高速传输数据。

On the other hand, adaptive modulation technique can enhance data rate, spectrum efficiency and transmission reliability in MIMO-OFDM systems.

另一方面，对于MIMO - OFDM系统来说，自适应调制技术可以提高系统的数据传输率、频谱效率以及传输的可靠性。

This modulation rate of data transmission is expressed as 12,800 baud (Bd), representing 12,800 bits per second.

这种数据传输调制频率用12800波特(Bd)来表示，指的是每秒钟12800位。

The data transmission rate will be increased to a large extent due to the advanced modulation in the task. The technique being used in practice will be useful in terms of economic and social aspects.

由于在本课题中采用了新的调制方式，提高了数据传输的速率，在今后的实际应用中，一定会有很好的经济效益和社会效益。
