  • 基于數(shù)據(jù)符號(hào)同步的FPGA仿真實(shí)現(xiàn)

    近年來(lái),人們對(duì)無(wú)線數(shù)據(jù)和多媒體業(yè)務(wù)的需求迅猛增加,促進(jìn)了寬帶無(wú)線通信新技術(shù)的發(fā)展和應(yīng)用。正交頻分復(fù)用 (Orthogonal Frequency Division Multiolexing,OFDM)技術(shù)已經(jīng)廣泛應(yīng)用于各種高速寬帶無(wú)線通信系統(tǒng)中。然而 OFDM 系統(tǒng)相比單載波系統(tǒng)更容易受到頻偏和時(shí)偏的影響,因此如何有效地消除頻偏和時(shí)偏,實(shí)現(xiàn)系統(tǒng)的時(shí)頻同步是 OFDM 系統(tǒng)中非常關(guān)鍵的技術(shù)。 本文討論了非同步對(duì) OFDM 系統(tǒng)的影響,分析了當(dāng)前用于 OFDM 系統(tǒng)中基于數(shù)據(jù)符號(hào)的同步算法,并簡(jiǎn)單介紹非基于數(shù)據(jù)符號(hào)同步技術(shù)。基于數(shù)據(jù)符號(hào)的同步技術(shù)通過(guò)加入訓(xùn)練符號(hào)或?qū)ьl等附加信息,并利用導(dǎo)頻或訓(xùn)練符號(hào)的相關(guān)性實(shí)現(xiàn)時(shí)頻同步。此算法由于加入了附加信息,降低了帶寬利用率,但同步精度相對(duì)較高,同步捕獲時(shí)間較短。 隨著電子芯片技術(shù)的快速發(fā)展,電子設(shè)計(jì)自動(dòng)化 (Electronic DesignAutomation,EDA) 技術(shù)和可編程邏輯芯片 (FPGA/CPLD) 的應(yīng)用越來(lái)越受到大家的重視,為此文中對(duì) EDA 技術(shù)和 Altera 公司制造的 FPGA 芯片的原理和結(jié)構(gòu)特點(diǎn)進(jìn)行了闡述,還介紹了在相關(guān)軟件平臺(tái)進(jìn)行開(kāi)發(fā)的系統(tǒng)流程。 論文在對(duì)基于數(shù)據(jù)符號(hào)三種算法進(jìn)行較詳細(xì)的分析和研究的基礎(chǔ)上,尤其改進(jìn)了基于導(dǎo)頻符號(hào)的同步算法之后,利用 Altera 公司的 FPGA 芯片EP1S25F102015 在 OuartusⅡ5.0 工具平臺(tái)上實(shí)現(xiàn)了 OFDM 同步的硬件設(shè)計(jì),然后進(jìn)行了軟件仿真。其中對(duì)基于導(dǎo)頻符號(hào)同步的改進(jìn)算法硬件設(shè)計(jì)過(guò)程了進(jìn)行了詳細(xì)闡述。不僅如此,對(duì)于基于 PN 序列幀的同步算法和基于循環(huán)前綴 (Cycle prefix,CP) 的極大似然 (Maximam Likelihood,ML)估計(jì)同步算法也有具體的仿真實(shí)現(xiàn)。 最后,文章還對(duì)它們進(jìn)行了比較,基于導(dǎo)頻符號(hào)同步設(shè)計(jì)的同步精度比較高,但是耗費(fèi)芯片的資源多,另一個(gè)缺點(diǎn)是沒(méi)有頻偏估計(jì),因此運(yùn)用受到一定限制。基于 PN 序列幀的同步設(shè)計(jì)使用了最少的芯片資源,但要提取 PN 序列中的信號(hào)數(shù)據(jù)有一定困難。基于循環(huán)前綴的同步設(shè)計(jì)占用了芯片 I/O 腳稍顯多。這幾種同步算法各有優(yōu)缺點(diǎn),但可以根據(jù)不同的信道環(huán)境選用它們。

    This section contains a brief introduction to the C language. It is intended as a tutorial on the language, and aims at getting a reader new to C started as quickly as possible. It is certainly not intended as a substitute for any of the numerous textbooks on C. 2. write a recursive function FIB (n) to find out the nth element in theFibanocci sequence number which is 1,1,2,3,5,8,13,21,34,55,…3. write the prefix and postfix form of the following infix expressiona + b – c / d + e * f – g * h / i ^ j4. write a function to count the number of nodes in a binary tr

    TFIND searches for one or more strings (boolean AND) in a text file. TFIND reports all lines where the string(s) were found (or NOT found by option). The search can be limited to a field in a fixed field (i.e. column oriented) list. An extended search mode is available, where only letters and digits are relevant. Other options: case sensitive search, alternative errorlevel with number of hits, header line with file name, LFN, custom prefix
