Product Introduction
MKQ-630S QPSK Modulator for Digital Television adopts advanced digital signal processing technology, fully in line with DVB-S standards, the receiver can be directly used for receiving digital satellite receiver. It not only can achieve a higher utilization of the spectrum, has a strong anti-interference and a higher cost performance, and FM analog and microwave equipment can be very good compatibility. QPSK modulation for digital television in the handling of data flow on the energy use of the proliferation of random treatment, RS coding, convolution intertwined, and contract convolutional code, modulation before forming the base-band processing to ensure that the data transmission performance. QPSK modulation for digital TV can transform the original TV microwave, with 30 M bandwidth transmission 5-8 sets of DVD images to achieve the effect of programs. FM microwave can also use the price of the effect of MMDS, to the realization of the entire launch. Encrypt the digital signal to ensure that images have not any damage.
