QPSK digital TV modulator adopts advanced digital signal processing
technology , of which receiving port can directly use digital
satellite receiver for receiving , thus fully complying DVB-S
standard .Not only can it gain relatively high frequency spectrum
usage ratio, having very strong anti-interference and relatively
high price performance to price ratio, but also it is well
compatible with microwave equipment. QPSK digital TV modulator
adopts various processing methods, such as random energy spread
processing, RS coding, convolution interweave, contracting
convolution coding, and pre-modulating baseband shaping peocessing,
etc. All these contribute a high guarantee to the data transmitting
performance .In a word, it¡¯s a high performance QPSK modulator for
transmitting digital TV and other digital signal. Features
