Detailed Description

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.
