无线激光通信系统中 DPIM 技术研究
Research on DPIM technology in wireless laser communication systems
摘要
Abstract
To improve the bandwidth efficiency,power demand of communications and anti-jamming capability of signal trans-mission in channels,we mainly study Digital Pulse Interval Modulation (DPIM)mode applied in wireless laser communication systems and compare by simulation and analysis the power,bandwidth,unit signaling rate and error performance of OOK, PPM,DPPM and DPIM mode.In addition,we design a FPGA-centered DPIM system on the basis of the theoretical analysis of DPIM.The results show that this system is stable in performance and can achieve high modulation rate.关键词
