HART Communication Foundation - Universal Command Specification

说明：  该程序给出了利用Saleh模型进行功率放大器预失真的过程．(The program gives the power amplifier pre-distortion with Saleh models.)

移动通信学习课件，非常详细，适合初学者，参考价值很高！1(Mobile learning courseware, very detailed, suitable for beginners, very useful! 1)

叠加训练序列的最小二乘信道估计与最小均方误差均衡，QPSK调制，做了4次迭代估计的性能对比。(superimposed training, least squares (LS) channel estimation, MMSE equalizer, QPSK modulation, 4 times iteration.)

说明：  使用matlab编写LDPC码，参考学习编程思路。(non-binary code, matlab)

说明：  距离多普勒算法，其中含有调频信号频谱图，以及后向投影算法的程序展示，关于合成孔径雷达的算法解释(Range Doppler algorithm, which contains FM signal spectrum, as well as back projection algorithm program display, on the synthetic aperture radar algorithm explanation)

串口通讯技术实现--两台pc机通过串口通讯（C语言）并可以调整波特率，奇偶校验位等。 (Serial Communication Technology- two pc machine through serial communication (C language) and can adjust the baud rate, parity bit and so on.)

提供通讯录成员的查询、增加、更新及删除等功能。(Provide contacts membership query, add, update, and delete functions.)

1962年Gallager提出LDPC的博士论文，堪称经典(1962 Gallager LDPC proposed doctoral dissertation, a classic)

LDPC校验矩阵生成、高斯消去法编码、BP译码程序，可以作为自己编写LDPC编译码程序的参考。因为matlab代码效率不高，所以这个程序仿真起来比较慢.(LDPC check matrix generation, Gaussian elimination coding, BP decoding procedure can be used as its own procedures for the preparation of LDPC codec reference. Because matlab code efficiency is not high, so this process is relatively slow simulation together.)
