[VHDL-FPGA-Verilog] fpga DL : 0: 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.

[3G develop] s02-5 DL : 0: Power consumption is an important design criterion in the design of wireless sensor networks. Hybrid radio frequency/free space optical wireless sensor networks (RF/FSO WSN) have been proposed to reduce the energy consumption of traditional RF-based sensor networks. This paper compares the performance of such a hybrid sensor network against the wellknown RF-based low energy adapting clustering hierarchy (LEACH) WSN proposed in the literature. Network performance is studied in terms of network lifetime and average network area coverage. Simulations show that despite not employing data aggregation, the RF/FSO WSN has a longer lifetime and larger average network coverage when compared to the LEACH WSN

[Program doc] 5-Mbps-optical-wireless-communication-with-error- DL : 0: One issue with underwater sensors is how to efficiently transfer large amounts of data collected by the node to an interrogating platform such as an underwater vehicle. It is often impractical to make a physical connection between the node and the vehicle which suggests an acoustic or optical wireless solution. For large amounts of data, the high bandwidth of underwater optical wireless is an advantage. A small, low-cost platform to demonstrate the potential of an optical wireless communications interface for underwater sensor nodes is demonstrated. To enhance the reliability and robustness of the optical wireless communication digital signal processing and error correction techniques are used. The system was tested in 3 and 7.7 meter tanks at 5 Mbps with the turbidity of the water controlled by the addition of Maalox.-One issue with underwater sensors is how to efficiently transfer large amounts of data collected by the node to an interrogating platform such as an underwater vehicle.
