對射頻設計者來說,高速的信號處理器加上高性能的數模/模數轉換器的進步,使得將更高的中頻數字化成為可能。從而進一步減少了射頻(RF)部分,并且在整體上提高了射頻(RF)部分的性能。圖1-1是一個現代無線數字接收機的功能模塊框圖。這里,射頻的模擬部分被限制在信號前端,而幾乎全部的基帶和中頻(IF)處理都是數字實現的。詳細介紹在射頻(RF)和中頻(IF)中所應用到的現代方法,這本書的其它章節將進一步介紹數字信號處理和傳輸數據的解碼

I always believe that one will easily lag behind unless he keeps on learning. Of course, if I am given a chance for advanced studies in this famous University , I will stare to effort to master a good command of advance my capability.

Imagine that you are a web developer (which is probably not a stretch if you are reading this book) and you are being encouraged to add some Ajax features to a site you’re working on. Maybe the originator of this request is your boss or your boss’s boss, who is not even sure what Ajax is, let alone what kinds of features might be useful.And maybe you’re not sure yourself. Imagine that your prior experience has mostly been on the server-side, developing in Java or some other server-side technology, and your experience with HTML and JavaScript has been fairly limited.This is the scenario we will explore over the next several chapters as you are introduced to the Dojo Toolkit.

wireless tools: used to manipulate the Wireless Extensions. The Wireless Extensions is an interface allowing you to set Wireless LAN specific parameters and get the specific stats. It also contains the IfRename package, used for advance renaming of network interfaces. We have cross compile to arm linux. and fixed some bug (eg:sometime the essid will be rename to a long name, or sometime it will disaply the essid twice)

linux下快速進入目錄的工具 qdir 解壓后運行install即可,最好將qd.sh文件的倒數第而行改為rm -rf "$QD"。比如在工作目錄下 \home\AAA\BBB\CCC\DDD\EEE\FFF\GGG,運行qd –s . 即可,用qd –e可以看到: 1 \home\AAA\BBB\CCC\DDD\EEE\FFF\GGG 我們又到一個目錄,\home\MyName\ AAA\BBB\CCC\DDD\EEE\FFF\GGG, 運行qd –s . 2,可以將這個目錄設置在第二個位置,用qd –e可以看到: 1 \home\AAA\BBB\CCC\DDD\EEE\FFF\GGG 2 \home\MyName\ AAA\BBB\CCC\DDD\EEE\FFF\GGG 這樣我們在任何目錄下,鍵入qd –e 1就立刻進入\home\AAA\BBB\CCC\DDD\EEE\FFF\GGG目錄,鍵入qd –e 2就立刻進入\home\MyName\ AAA\BBB\CCC\DDD\EEE\FFF\GGG ,可以做到工作目錄瞬間轉換。

如今的移動電話不僅要支持蜂窩頻率,還要支持那些用于移動電視、藍牙、WLAN和定位服務的非蜂窩特性。由于每次手機換代都縮小了天線的可用空間,天線被包在相機和鍵盤電路周圍并重新安排路徑,導致天線效率降低。一部分性能損失可以通過天線調諧得到恢復,即使用動態阻抗調諧技術根據工作頻率和環境條件優化天線的性能。然而,所面臨的挑戰是,任何成功的天線調諧方案均須滿足損耗低、線性度高、能夠處理很高強度的RF信號且耗能少的要求。

To write data to the FIFO, present the data to be written and assert the write enable. At the next rising edge of the clock, the data will be written. For every rising edge of the clock that the write enable is asserted, a piece of data is written into the FIFO. If the FIFO has data in it, the value at the head of the FIFO is present on the FIFO data output. To read data from the FIFO, assert the read enable. At the next rising edge of the clock, capture the data output the FIFO will subsequently advance to the next piece of data stored in the FIFO.
