We simulate uncoded BER of BPSK modulated data as a function of SNR -in an AWGN channel -in a Rayleigh fading channel -in an AWGN channel when direct sequence spreading is used and compare results to the theoretical ones. We assume coherent receiver and perfect synchronization.

使用AVR ATmega128實驗箱上的資源，設(shè)計萬年歷。本系統(tǒng)應(yīng)用了Text LCD，矩陣鍵盤，定時器/計數(shù)器中斷系統(tǒng)，另外，我從伺服電機接口PB.5接出一個蜂鳴器。本次實驗的目的就是熟悉AVR的這些資源。

要將商品行情軟件的數(shù)據(jù)導(dǎo)入自己的數(shù)據(jù)庫，除了要知道商品軟件數(shù)據(jù)的數(shù)據(jù)結(jié)構(gòu)，同時還與你自己數(shù)據(jù)庫的數(shù)據(jù)結(jié)構(gòu)有關(guān)。一般情況下，業(yè)余愛好者往往都是使用ASCII即text文本結(jié)構(gòu)。text格式的數(shù)據(jù)易讀易懂，可以讓許多國際股票軟件和工具軟件(比如：GET\TT\SUPERCHART\SSPS\EXECL等等)直接調(diào)用。

Tiny Planet is small device connected to a GSM cell phone. When the mobile receives a predefined SMS (text message), like "Activate burglar alarm" or "Start backup pump", the circuit automatically recognizes it as a command, and switches the output port accordingly. Besides switching the port on or off, the user can pulse it for a short period (e.g. 鈥淩eboot remote server鈥?.
