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.
