| 摘 要： | 无线个域网是当前无线通信研究的热点之一,IEEE802.15.3a对发射信号的功率、短距离的高速率信息传输等方面提出了更高的要求。由于FCC对超宽带信号进行了重新定义,使得产生超宽带信号的方式并不局限在冲激无线电范畴,利用OFDM技术与DS CDMA技术也能实现超宽带通信。当前IEEE802.15.3a的2种主流技术(MB OFDM和DSCDMA)之间争执不下,将对2种技术进行详细的比较,比较结果显示,在当前的技术水平下,MB OFDM技术具有一定的优势。

| Abstract: | Wireless personal area network is the hot spot problem in the present wireless communication area.It is stricted with the power of transmitting signals and shorthaul high speed information transmission in IEEE802.15.3a.Because FCC has redefined the ultrawideband signal,it is not produced by the impulse radio.If using OFDM and DSCDMA,ultrawideband communication can also be realized.In present literature.it has not obvious advantage.This article will particularly compare with MBOFDM and DSCDMA.The MBOFDM is better than DSCDMA after compared their performance. |
