| 摘 要： | 使用WiFi(Wireless Fidelity)IEEE 802.11b/g协议的无线局域网(WLAN)技术已经成为PC和笔记本电脑的标准而正在快速扩散到PDA(Personal Digital Assistant)和其它便携式设备。与此同时,蓝牙作为耳机,麦克风连到各种个样的无线设备的串口线的替代品已经越来越普遍。这两种无线协议都工作于2.40至2.48GHzISM(工业,科学和医疗)射频带。WiFi使用12个带宽为22MHz重叠的频道其中一个,而蓝在带宽为79MHz范围跳频3]。因此,无论WiFi正在使用哪个频道两个系统间会存在互相干扰和共存的问题导致数据吞吐量的降低。实现IEEE802.11 WLAN协议的设使用FEC(Foward Error Correction)纠错技术来减轻于其它无线网的干扰。在该文中,我们将对RS(Reed Solomon)编码与BS(Binary Convolutional)编码使用于解决WLAN于BT共存问题的相对有效性进行一个调查并作出结论。

| Abstract: | WLAN(Wireless Local Area Network) devices that implement the Wifi(Wireless Fidelity) IEEE802.11b/g protocol have already become standard additions to Desktop and Laptop computers and are spreading to Personal Digital Assistants(PDA) and other portable devices at a rapid rate.At the same time,ear phones and microphones that use BT(Bluetooth) as a wireless replacement for the serial cable when connecting to all sorts of wireless devices are becoming increasingly common.These two wireless protocols both operat... |
