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.
