Description: 无线光通信技术具有通信容量大、传输速率高等众多优点, 在许多场合都有重要的应用, 是现代通信技术研究的一个热点。由于脉冲位置调制 ( PPM ) 有较高的平均功率利用率和抗干扰能力, 故 PPM是无线光通信系统中常用的调制方式。在研究 PPM调制技术的基础上, 就基于 FPG A的无线光通信 PPM调制系统进行设计, 并用 V H D L语言完成了系统的设计和仿真。仿真结果表明, 该设计具有正确性和合理性。-Wireless optical communication technology has the communications capacity, many of the benefits of higher transmission rates, in many occasions have important applications in modern communication technologies are a hot research. Because of pulse position modulation (PPM) have a higher average power utilization and anti-interference ability, so PPM is a wireless optical communication system commonly used in modulation. PPM modulation technique in the study on the basis of FPG A based on wireless optical communication PPM modulation system design, and VHDL language achieve the system design and simulation. Simulation results show that the rationality of the design right.
