Abstract
With the rapid development of remote sensing technology, the requirements on the rates of remote sensing data and coding performance become more and more strict. Under high bit rates and complicated coding conditions, designing demodulator with high bit rate to meet the Consultative Committee for Space Data Systems(CCSDS) standard becomes the key to solve the remote sensing satellite data demodulation. In the demodulator structure of the software radio platform, the characteristics of Low Density Parity Check Code(LDPC) decoding are analyzed, the designs of decoding module structure, the demodulation rate and the storage rules are completed. The design results meet the requirements on high bit rate sensing satellite demodulator, which improves the lower transmission efficiency of data and the use efficiency of space resources.关键词
