西門子CNC系統編程代碼表,對初學者幫助很大(Siemens CNC system control code )

OPC通讯源代码C++编写，第一次发文，从别处下载而来(OPC communication source code is written in C++, for the first time issued a document downloaded elsewhere)

高通，rex，OS，很好的文档~~~！！！(Qualcomm, rex, OS, a very good document ~ ~ ~)

通信物理层处理，包括发射机和接收机，内容有前导处理，信道估计，信道编解码，BPSK、QPSK和8PSK调制与解调等。(Communication the physical treatment, including the transmitter and receiver, the content is leading processing, channel estimation, channel decoding, BPSK QPSK and eight PSK modulation and demodulation, etc )

这是一套GPS定位采集程序，可用于卫星天线乏味俯仰角的计算(This is a set of GPS positioning acquisition procedures can be used for satellite antenna pitch angle tedious calculation)

说明：  SCMA系统中的PM-MPA检测，信道采用瑞利信道，迭代次数为6(For PM-MPA detection in SCMA system, Rayleigh channel is adopted and the number of iterations is 6)

说明：  polar 代码，使用matlab进行仿真，实现了polar代码基本功能，并提供polar基本原理说明(matlab polar simulation)

有助于学习LS信道估计的编码,以及mmse和LMMSE(ls chanel MMSE CHANEL LMMSE CHANEL)

说明：  基于quartus的布斯乘法器的verilog 实现。布斯乘法算法是计算机中一种利用数的2的补码形式来计算乘法的算法。该算法由安德鲁·唐纳德·布斯于1950 年发明，当时他在伦敦大学伯克贝克学院做晶体学研究。布斯曾使用过台式计算器，由于用这种计算器来做移位计算比加法快，他发明了该算法来加快计算速度。(The verilog codes of booth multiplier based on quartus. Booth multiplication algorithm is a computer algorithm using the complement form of number 2 to calculate the multiplication. The algorithm was invented in 1950 by Andrew Donald booth, who was working on crystallography at birkbeck college, university of London. Booth used a desktop calculator, and because it was faster to do shifts than to add, he invented the algorithm to speed up the calculations.)
