Analysis of DPPM-Coded Modulation Signals

Differential pulse-position modulation (DPPM) is a type of pulse-position modulation (Ke Xizheng, Xi Xiaoli. Introduction to wireless laser communication [M]. Beijing University of Posts and Telecommunications Press, August 2004; Wang Jingyuan, Zhang mainline. PPM modulation in optical wireless communication [J]. Telecommunications technology, 2000 (5): 81- 84.;Pang Zhiyong and Dazhi in Journal of Guilin Institute of electronic technology 22:1–4, 2002;Jianzhong and Ying in Optical communication technology. 15:45–46, 2006;), similar to pulse-position modulation (PPM) and multipulse position modulation (MPPM). This chapter analyzes the bit-error rate characteristics of DPPM-coded modulation, introduces the implementation mode of DPPM-coded modulation, and finally provides a hardware-implementation scheme for coded modulation.
