OFDM(正交頻分復(fù)用)技術(shù)實(shí)際上是MCM(Multi-Carrier Modulation，多載波調(diào)制)的一種。其主要思想是，將信道分成若干正交子信道，將高速數(shù)據(jù)信號轉(zhuǎn)換成并行的低速子數(shù)據(jù)流，調(diào)制到在每個子信道上進(jìn)行傳輸。正交信號可以通過在接收端采用相關(guān)技術(shù)來分開，這樣可以減少子信道之間的相互干擾(ICI)。每個子信道上的信號帶寬小于信道的相關(guān)帶寬，因此每個子信道上的可以看成平坦性衰落，從而可以消除符號間干擾。而且由于每個子信道的帶寬僅僅是原信道帶寬的一小部分，信道均衡變得相對容

Multi-carrier modulation? Orthogonal Frequency Division Multi- plexing (OFDM) particularly? has been successfully applied to a wide variety of digital communications applications over the past several years. Although OFDM has been chosen as the physical layer standard for a diversity of important systems? the theory? algorithms? and implementation techniques remain subjects of current interest. This is clear from the high volume of papers appearing in technical journals and conferences.

Since the principle of multi-carrier code division multiple access (MC-CDMA) was simultaneously proposed by Khaled Fazel et al. and Nathan Yee et al. at the IEEE International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC) in the year 1993, multi-carrier spread spectrum (MC-SS) has rapidly become one of the most wide spread independent research topics on the field of mobile radio communications. Therefore, the International Workshop on Multi-Carrier Spread Spectrum (MC-SS) was initiated in the year 1997. Multi-carrier and spread spectrum systems with their generic air interface and adaptive technologies are considered as potential candidates to fulfill the requirements of next generation mobile communications systems.

Notwithstanding its infancy, wireless mesh networking (WMN) is a hot and growing field. Wireless mesh networks began in the military, but have since become of great interest for commercial use in the last decade, both in local area networks and metropolitan area networks. The attractiveness of mesh networks comes from their ability to interconnect either mobile or fixed devices with radio interfaces, to share information dynamically, or simply to extend range through multi-hopping.

UCGUI最新版源碼簡介 UCGUI3.90版源碼有如下幾點(diǎn)新的變化. 1.這個版本的UCGUI提供了模擬器的源碼(早知我不用那么辛苦反編譯出模擬器源碼了,不過大家可以比較一下看). 2.還有JPEG圖版支持 3.ListView控件支持. 4.Menu菜單支持. 5.ScrollBar滾動條支持. 6.multi-controller多控制器支持. 另外源碼上還有很多的調(diào)整, 將控件的功能分開到各個文件當(dāng)中更易于將來擴(kuò)充, 大家仔細(xì)看看
