Product Details

Introduction:

Our company is a remote sensing satellite ground system manufacturer. The high-speed digital demodulator is a comprehensive processing device integrating dual-channel frequency conversion, modulation, encoding, demodulation, decoding, storage, carrier acquisition, tracking, synchronization, spectrum display and signal analysis. The demodulator provides a real-time data demodulation and decoding service for satellite ground systems and ground stations. The IF of demodulaor can support 720MHz, 1.2GHz, 1.5GHz, modulation mode can support PSK, QAM, APSK, GMSK, etc., decoding mode can support RS, Viterbi, RS+Viterbi, LDPC, DVB-S2 mode,

etc. 

The high-speed digital demodulator has applied for 8 patents with series technologies such as continuous variable rate parallel demodulation algorithm, parallel carrier recovery and parallel clock recovery technology, parallel frequency domain equalization technology, parallel LDPC decoding implementation technology, etc. It also adapts to a variety of modulation and decoding methods and the demodulator has been successfully delivered to customers in Ukraine, Brazil, Venezuela and other countries. we can also supply the customize demodulator equipment according to customer needs.

and the delivery date is completed within three months after the order is placed.
