Finally, all the modules are integrated to establish a fundamental OFDM base-band processing system.
最后利用这些模块组建了最基本的OFDM基带信号处理系统。
OFDM can simplify the base-band processing unit of the receiver greatly and can increase the data rate.
OFDM可以使接收机中的基带处理单元大大简化，并且可以提高数据速率。
When processing digital base-band, the signal of pilot-frequency was taken out from normal carrier channel and it would be used for transmitting pseudo pilot-frequency.
在数字基带处理时，从正常载频信道中提取出导频信号，用于伪导频的发射。
AIS system is composed with communication processing module, base band processing module, radio module and interface module.
AIS系统由通信处理模块、基带处理模块、射频模块和接口模块组成。
Then we perform digital pre-compensation method, which can be used in the processing of base band signal to reject image frequency and protect carrier leak to meet the application purpose.
然后采用对基带信号的数字预补偿方法来抑制镜像频率和载波泄漏，从而达到应用的目的。
Then we perform digital pre-compensation method, which can be used in the processing of base band signal to reject image frequency and protect carrier leak to meet the application purpose.
其思路是将信号先通过单边带调制，将较低频率调制到需要的频率范围；然后采用对基带信号的数字预补偿方法来抑制镜像频率和载波泄漏，从而达到应用的目的。
