Simulate, by using c++ ,a communication system consists of binary source, RS(7,3,5)/RS(128,122,7) encoder, BPSK modulator, AWGN channel, coherent demodulator, RS(7,3,5)/RS(128,122,7) BM decoder and sink。-Simulate, by using c, a communication system consists of binary source, RS (7,3,5)/RS (128,122,7) encoder, BPSK modulator, AWGN channel, coherent demodulator, RS (7,3,5 )/RS (128,122,7) BM decoder and sink.

瑞利分布，主要实现锐利分布的某些特征，非常的不错。-Rayleigh distribution, mainly the distribution of certain characteristics to achieve sharp, very good.

DTMF实时解码，采用goertzel算法，通过监测信号中的两个主要频率从而得出DTMF值-DTMF decoder in real time, using goertzel algorithm, by monitoring the signal so as to arrive at the two main frequency DTMF value

Abstract: By using gateway systems on large 32-bit platforms, networks of small, 8- and 16-bit microcontrollers can be monitored and controlled over the Internet. With embedded Linux, these gateways are easily moved from full-blown host PCs to embedded platforms like the PC104. In this class you will learn about hardware platforms that support embedded Linux, Linux kernel configuration, feature selection, installation, booting and tuning.
