摘要

为了改善通信的带宽效率、功率需求

以及信道中信号传输的抗干扰性能

对应用于无线激光通信系统中的DPIM（数字脉冲间隔调制）方式进行了研究。通过仿真分析

比较了OOK（开关键控）、PPM（脉冲位置调制）、DPPM（差分脉冲位置调制）以及DPIM方式的功率、带宽、单位传信率和差错性能。根据DPIM的理论分析

设计了一种以FPGA（现场可编程门阵列）为核心的DPIM系统。结果表明

该调制系统性能稳定

可以达到较高的调制速率。

Abstract

To improve the bandwidth efficiency

power demand of communications and anti-jamming capability of signal transmission 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.
