这是一个学习Symbian的ListBox的好例子,我也是看学个学会的(This is a learning Symbian a good example of the ListBox, I also watch a Institute of Science)

某智能设备公司开关量采集系统（Modbus RTU），很不错哦！对于该类设备基本上都可以通用，只是“寄存器地址”不一样。我就参照该源程序写了一款SOS应急呼叫系统、酒店客房插卡取电、退房呼叫系统等。保证原创，独一无二。(A smart device switch acquisition system (Modbus RTU), very good, oh! Can be generic, such equipment is basically just not the same register address. I refer to the source Admission card, write a SOS emergency call system, hotel rooms, check out the call system. Guaranteed original, unique.)

卫星通讯DVBS2 中对编码性能测试，通过比较最后的误码率和信噪比的关系，判断结果(satellite communication)

给出了BPSKMSKQAMGMSK的详细代码，可以直接在MATLAB中运行，并且有误码率的仿真。(BPSKMSKQAMGMSK given a detailed code, can be run directly in MATLAB, and BER simulation.)

comparison of BER performance for mapping of turbo coding with 16QAM 64QAM 128QAM

仿真了高斯白噪声，并通过巴特沃夫滤波器生成高斯色噪声(The gaussian noise was simulated and the gaussian noise was generated through the butterworth filter)

GD32F库函数，各种外设，gpio等等(gd32 library v2.0.0 gpio ..)

一个可以用语音modem录音放音的Delphi控件源码(A modem with voice recording playback control of Delphi source code)

code OFDM Matlab use in MIMO

常用数字调制技术，包括BPSK，OQPSK，QPSK，MSK，GMSK，QAM等的调制解调仿真程序，并且包含AWGN及衰落信道下的仿真，对学习数字调制技术有较大帮助(Commonly used digital modulation techniques, including BPSK, OQPSK, QPSK, MSK, GMSK, QAM modulation and demodulation simulation program such and includes AWGN and fading channel simulation, the study of digital modulation techniques of great help)
