Outline
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 ratio, but also it can well comply analogue
FM microwave equipment.
QPSK digital TV modulator adopts various processing method, such as
random energy spread processing, RS coding, convolution interweave,
contracting convolution coding, and pre-modulating baseband shaping
processing, etc. all these contribute a high guarantee to the data
transmitting performance.
