Design And Implementation Of DSP Algorithms In The Simulation Platform Of Deep Space Communications

Deep space exploration and use is always human ideal. To carry out deep space exploration, in addition to the launch of the detector, control technology, deep space communications plays an important role. In deep space communications system, in addition to the image of the source coding, channel error correction coding, modulation, communication network system, the research of communications simulation platform has very important significance of deep space communications system.In this paper, combined with the characteristics of deep-space communications, a detailed research of LDPC, TURBO, BPSK, MSK and adding noise to the channel, focus on the optimization of DSP algorithms. Based on the ADSP TS201, on deep-space communications source coding, modulation, adding noise to channel, demodulation and source decoding optimized, greatly reducing delay of running. Loading the optimized results to the hardware simulation platform, the simulation results show that the system can implement the entire process of deep space communications, and meet the system requirement of real-time.
