Abstract

Taking the deep space laser communication as the application background, based on multi-pulse position modulation and differential pulse position modulation, a new differential multi-pulse position modulation (DMPPM) mode is proposed. The DMPPM theory model is set up, and a comparative study and analysis of four modulation schemes of PPM, DPPM, MPPM and DMPPM has been developed. The simulation results show that the repetition rate of the pulse laser has a great influence on the four modulation modes. DMPPM has the characteristics of the smallest average symbol length, the largest average transmitting power, the maximum peak transmitting power, the maximum unit transmission rate, the smallest bandwidth demand and a higher transmission efficiency. The analysis shows that DMPPM is greatly influenced by the repetition frequency of the laser. It is very necessary to improve the repetition rate of the laser under the premise of ensuring the peak power of the pulse laser. DMPPM can become one of the excellent modulation schemes for deep space laser communication.
