This paper reports two computerized methods for decoding the digital base band signal obtained from meteorological satellite.

论述利用计算机对气象卫星数字基带信号解码的两种方法。

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。

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。

For example you might have Texas Instrument or TI which is the biggest supplier in the base-band market or DSP (Digital Signal Processing) but still have competition from the likes of Lucent, Motorola, Qualcomm.
