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实验箱上的资源，设计万年历。本系统应用了Text LCD，矩阵键盘，定时器/计数器中断系统，另外，我从伺服电机接口PB.5接出一个蜂鸣器。本次实验的目的就是熟悉AVR的这些资源。

source code for awgn,BPSK modulation and demodulation,channel simulation,convolution encoder,data generator,encoder and fading channel

要将商品行情软件的数据导入自己的数据库，除了要知道商品软件数据的数据结构，同时还与你自己数据库的数据结构有关。一般情况下，业余爱好者往往都是使用ASCII即text文本结构。text格式的数据易读易懂，可以让许多国际股票软件和工具软件(比如：GET\TT\SUPERCHART\SSPS\EXECL等等)直接调用。 ...

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 ...
