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 digitalTV
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,its a high performance QPSK modulator for transmitting
digital TV and other digital signal.
