QPSK digital modulator

Description

Product descriptions QPSK modulation for digital television using advanced digital signal processing technology, full compliance with DVB-S standard, the receiving end can be directly used for receiving digital satellite ***** must not only be able to achieve a higher utilization of the spectrum, with a strong anti-jamming and high ***** microwave equipment and simulation and will be 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 that the data transmission performance. Performance characteristics for the original television microwave transformation *0M available bandwidth transmission of the results from five to eight sets of DVD images 1. for the original television microwave transformation *0M available bandwidth transmission of the results from five to eight sets of DVD images 2. Use of the MMDS frequency microwave achieve the price effect to the realization of launch 3. can be digitally encrypted, with no damage to the image
