第一節(jié)、samba是干什么的？它有什么用？ Samba（SMB是其縮寫(xiě)） 是一個(gè)網(wǎng)絡(luò)服務(wù)器，它是Linux作為本地服務(wù)器最重要的一個(gè)服務(wù)，用于Linux和Windows共享文件之用；Samba可以用于Windows和 Linux之間的共享文件，也一樣用于Linux和Linux之間的共享文件；不過(guò)對(duì)于Linux和Linux之間共享文件有更好的網(wǎng)絡(luò)文件系統(tǒng) NFS，NFS也是需要架設(shè)服務(wù)器的； 2、安裝及服務(wù)操作命令 安裝samba程序非常簡(jiǎn)單，使用rpm -q samba查看當(dāng)前系統(tǒng)是否已經(jīng)安裝了samba軟件。 如果沒(méi)有那就進(jìn)入光盤(pán)，rpm -ivh *samba*.rpm即可。 仔細(xì)說(shuō)下安裝的包： samba-common-3.0.28-0.el5.8 //samba服務(wù)器和客戶(hù)端中的最基本文件 samba-3.0.28-0.el5.8 //samba服務(wù)器核心軟件包 system-config-samba-1.2.39-1.el5 //samba圖形配置界面 samba-client-3.0.28-0.el5.8 //samba客戶(hù)端軟件 啟動(dòng)、暫停和停止服務(wù)： /etc/init.d/smb start /etc/init.d/smb stop /etc/init.d/smb restart 或 service smb start service smb stop service smb restart 第二節(jié)、由最簡(jiǎn)單的一個(gè)例子說(shuō)起，匿名用戶(hù)可讀可寫(xiě)的實(shí)現(xiàn) 第一步： 更改smb.conf 我們來(lái)實(shí)現(xiàn)一個(gè)最簡(jiǎn)單的功能，讓所有用戶(hù)可以讀寫(xiě)一個(gè)Samba 服務(wù)器共享的一個(gè)文件夾；我們要改動(dòng)一下smb.conf ；首先您要備份一下smb.conf文件； [root@localhost ~]# cd /etc/samba [root@localhost samba]# cp smb.conf smb.conf.bak [root@localhost samba]# vi smb.conf 或geidt smb.conf & 然后我們把下面這段寫(xiě)入smb.conf中: [global] workgroup = WORKGROUP netbios name = Liukai server string = Liukai's Samba Server security = share [test] path = /opt/test writeable = yes browseable = yes guest ok = yes 注解： [global]這段是全局配置，是必段寫(xiě)的。其中有如下的幾行； workgroup 就是Windows中顯示的工作組；在這里我設(shè)置的是WORKGROUP （用大寫(xiě)）； netbios name 就是在Windows中顯示出來(lái)的計(jì)算機(jī)名； server string 就是Samba服務(wù)器說(shuō)明，可以自己來(lái)定義；這個(gè)不是什么重要的； security 這是驗(yàn)證和登錄方式，這里我們用了share ；驗(yàn)證方式有好多種，這是其中一種；另外一種常用的是user的驗(yàn)證方式；如果用share呢，就是不用設(shè)置用戶(hù)和密碼了； [test] 這個(gè)在Windows中顯示出來(lái)是共享的目錄； path = 可以設(shè)置要共享的目錄放在哪里； writeable 是否可寫(xiě)，這里我設(shè)置為可寫(xiě)； browseable 是否可以瀏覽，可以；可以瀏覽意味著，我們?cè)诠ぷ鹘M下能看到共享文件夾。如果您不想顯示出來(lái)，那就設(shè)置為 browseable=no，guest ok 匿名用戶(hù)以guest身份是登錄； 第二步：建立相應(yīng)目錄并授權(quán) [root@localhost ~]# mkdir -p /opt/test [root@localhost ~]# id nobody uid=99(nobody) gid=99(nobody) groups=99(nobody) [root@localhost ~]# chown -R nobody:nobody /opt/test 注釋?zhuān)宏P(guān)于授權(quán)nobody，我們先用id命令查看了nobody用戶(hù)的信息，發(fā)現(xiàn)他的用戶(hù)組也是nobody，我們要以這個(gè)為準(zhǔn)。有些系統(tǒng)nobody用戶(hù)組并非是nobody ； 第三步：?jiǎn)?dòng)服務(wù)器 第四步：訪問(wèn)Samba 服務(wù)器的共享； 1、在Linux 中您可以用下面的命令來(lái)訪問(wèn)； [root@localhost ~]# smbclient -L //liukai或 smbclient //192.168.0.94/test Password: 注：直接按回車(chē) 2、在Windows中，您可以用下面的辦法來(lái)訪問(wèn)； \\liukai 或 \\192.168.0.94 3、說(shuō)明：如果用了netbiosname，就可以用“\\主機(jī)名”來(lái)訪問(wèn)，如果沒(méi)用netbiosname，就不能用主機(jī)名訪問(wèn)。 第三節(jié)、簡(jiǎn)單的密碼驗(yàn)證服務(wù)器 修改smb.conf文件： security = user guest accouNT = liukai encrypt passwords = yes smb passwd file = /etc/samba/smbpasswd 然后，建立一個(gè)新用戶(hù) useradd liukai passwd liukai 成功后，cat /etc/passwd | mksmbpasswd.sh > /etc/samba/smbpasswd smbpasswd -a liukai 這就成功地添加了一個(gè)smb用戶(hù)。 重啟服務(wù)，使用這個(gè)用戶(hù)進(jìn)行登錄即可。

Multiuser multiple-input-multiple-output (MU- MIMO) systems are known to be hindered by dimensionality loss due to channel state information (CSI) acquisition overhead. In this paper, we investigate user-scheduling in MU-MIMO systems on accouNT of CSI acquisition overhead, where a base station dynamically acquires user channels to avoid choking the system with CSI overhead.

Cognitive radios have become a vital solution that allows sharing of the scarce frequency spectrum available for wireless systems. It has been demonstrated that it can be used for future wireless systems as well as integrated into 4G/5G wireless systems. Although there is a great amount of literature in the design of cognitive radios from a system and networking point of view, there has been very limited available literature detailing the circuit implementation of such systems. Our textbook, Radio Frequency Integrated Circuit Design for Cognitive Radios, is the first book to fill a disconnect in the literature between Cognitive Radio systems and a detailed accouNT of the circuit implementation and architectures required to implement such systems. In addition, this book describes several novel concepts that advance state-of-the-art cognitive radio systems.

Part I provides a compact survey on classical stochastic geometry models. The basic models defined in this part will be used and extended throughout the whole monograph, and in particular to SINR based models. Note however that these classical stochastic models can be used in a variety of contexts which go far beyond the modeling of wireless networks. Chapter 1 reviews the definition and basic properties of Poisson point processes in Euclidean space. We review key operations on Poisson point processes (thinning, superposition, displacement) as well as key formulas like Campbell’s formula. Chapter 2 is focused on properties of the spatial shot-noise process: its continuity properties, its Laplace transform, its moments etc. Both additive and max shot-noise processes are studied. Chapter 3 bears on coverage processes, and in particular on the Boolean model. Its basic coverage characteristics are reviewed. We also give a brief accouNT of its percolation properties. Chapter 4 studies random tessellations; the main focus is on Poisson–Voronoi tessellations and cells. We also discuss various random objects associated with bivariate point processes such as the set of points of the first point process that fall in a Voronoi cell w.r.t. the second point process.

An acronym for Multiple-In, Multiple-Out, MIMO communication sends the same data as several signals simultaneously through multiple antennas, while still utilizing a single radio channel. This is a form of antenna diversity, which uses multiple antennas to improve signal quality and strength of an RF link. The data is split into multiple data streams at the transmission point and recombined on the receive side by another MIMO radio configured with the same number of antennas. The receiver is designed to take into accouNT the slight time difference between receptions of each signal, any additional noise or interference, and even lost signals.
