JXDH-6502(A) QPSK Modulator



Outline

QPSK digital TV modulator adoptsadvanced digital signal processing technology, of which receiving portcan directly use digital satellite receiver for receiving, thus fullycomplying DVB-S standard. Not only can it gain relatively highfrequency spectrum usage ratio, having very strong anti-interferenceand relatively high price performance ratio, but also it can wellcomply analogue FM microwave equipment.

QPSK digitalTV modulator adopts various processing method, such as random energyspread processing, RS coding, convolution interweave, contractingconvolution coding, and pre-modulating baseband shaping processing,etc. all these contribute a high guarantee to the data transmittingperformance. In a word, its a high performance QPSK modulatorfortransmitting digital TV and other digital signal.
