c8051F系列单片机CAN总线的应用例程(c8051F Series Single-chip CAN bus application routines)

说明：  载波同步是QPSK信号相干解调的一项关键技术。(Carrier synchronization signal coherent QPSK demodulation is a key technology.)

OFDM系统中，部分传输序列PTS的算法源码((Orthogonal Frequency Division Multiplexing PTS)

说明：  Goertzel算法是DTMF信号检测的核心,它利用二极点的IIR滤波器计算离散傅立叶变换值,快速有效的提取输入信号的频谱(Goertzel algorithm is the core of DTMF signal detection. It uses the two-pole IIR filter to calculate the discrete Fourier transform value, and extracts the spectrum of input signal quickly and effectively.)

用51单片机完美地解决凝露现象。防止元件老化(The dew phenomenon can be perfectly solved by 51 single chip computer. Preventing component ageing)

封装了windows操作串口的几个API（CreateFile， ReadFile，WriteFile，SetComState）。串口的读写设置这几个操作都可以简单地只用关键一两个参数就能实现操作。也是一个很好的例子，我写这个之前查了不少资料，感觉非常麻烦，索性发出来给新手们作个样例(Windows serial COM port access class，it includes CreateFile, SetComState，ReadFile，WriteFile，CloseFile)

这个文件是讲大规模MIMO的scm模型的。代码容易看看懂(this document descpbe)

基于libmodbus编译，使用vs2013编译完整，亲测可行。(Compiled based on libmodbus, compiled using vs2013, complete, pro test feasible.)

HFSS 高低阻抗滤波器 5节，可调参数，优化(HFSS high and low impedance filter 5, adjustable parameters, optimization)

PC机MVB总线通讯测试程序（MVB从设备），PC机使用Duagon的MVB通讯卡。程序做为MVB的从设备，包括MVB驱动，MVB主配置，MVB端口通讯收发的例子。(PC, MVB bus communication test procedure (MVB from the device), the PC machine use Duagon the MVB communication card. Program as from MVB MVB driver, the MVB the main configuration, MVB port communications transceiver example.)
