生成一个一定参数的原信号，并附加一个符合均匀分布的随机噪声，分别画出该信号经过均匀采样的频谱图以及经过非均匀采样的频谱和时域图(Generate a certain parameter of the original signal, and attach a line with uniformly distributed random noise were drawn through uniform sampling of the signal spectrum as well as through non-uniform sampling of the spectrum and time domain)

This is a generic timer c code. Useful for detecting timeouts in embedded development. Some hardware timer irq must call its Tick function.

编写一个含QAM传输的发送和接收模块 1)分别采用复基带仿真和实带通仿真两种形式 a) 实带通仿真时, 载波频率为符号率的4倍 b)发端采用滚降系数0.5的根号升余弦滤波器 2)画出Eb/N0=15dB时的接收波形(收滤波前),取100个采样 3)画出发端输出的眼图和收端过匹配滤波后的眼图(画眼图时不加噪声) 统计误符号率和误比特率与Eb/N0的关系,画出曲线, 与理论计算的曲线相对比 (Prepare to send of one with QAM transmission and receiver module 1), respectively, the complex baseband simulation and the real band-pass simulation in two forms a) the real band-pass simulation, the carrier frequency used for the symbol rate of 4 times b) the originator roll-off factor of 0.5 root raised cosine filter, 2) draw Eb/N0 = 15dB when the received waveform (closing filter), take 100 samples) to draw the originator of the output eye diagram and income side of the eye diagram after the matched filter ( draw the eye diagram without noise) statistics symbol error rate and bit error rate and Eb/N0, draw a curve calculated with the theoretical curve compared)

说明：  RS码(Reed—Solomon码)是多进制BCH码，也是目前最有效、应用最广泛的差错控制编码。它具有很强的纠错能力，随机错误、突发错误都能纠正，特别是在短的和中等码长其性能接近于理论值。再加上构造方便，编码简单，设备不复杂，因此在实时性要求较高的数字通信及深空通信方面有广泛应用(RS code ( Reed- Solomon code ) is a multiple of BCH code, is currently the most effective, the most widely used error control coding. It has a strong error correction ability, random error, burst error can be corrected, especially on short and medium length code performance close to the theoretical value. Plus convenient construction, simple coding, equipment is not complex, so the real-time digital communication and deep space communication is widely used )
