Product descriptions

QPSK modulation for digital television use advanced digital signal processing technology,full compliance with DVB-S standard, the receiving end can be directly used for receiving digital satellite receiver.It can achieve a higher utilization of the spectrum, with a strong anti-jamming and high performance.FM microwave equipment has simulation and good compatibility.

Digital TV QPSK modulation in the treatment of the data flow of energy to deal with the proliferation of randomization, RS codeConvolution. Interleave contraction coding, modulation before forming the base-band processing to ensure the data transmission performance.

 

Performance characteristics

1. For the original television microwave transformation 30M available bandwidth transmission of the results from five to eight sets of DVD images.
2. Achieve the effect of MMDS at the price of frequency microwave and realize omni launch.
3. Can be digitally encrypted, with no damage to the image.
