Implementation of rs codes in matlab

关于滤波的设计 及示例,pdf格式，在matlab下设计完成！(the design for the filter!)

说明：  HMC1022的中文资料,资料比较难找~~~~(HMC1022 the Chinese datasheet)

根据直扩原理，首先有随机数发生器产生一系列二进制信息数据（+1，-1），每个信息比特重复Lc次，Lc对应每个信息比特所包含的伪码片数，包含每一比特Lc次重复的序列与另一个随机数发生器产生的PN序列c(n)相乘。然后在该序列上叠加高斯白噪声和形式为i(n)=Acosw0n余弦干扰下次信号，切余弦干扰信号的振幅满足条件A<Lc。在解调器中进行与PN序列的互相关运算，并且将组成各信息比特的Lc个样本进行求和。加法器的输出送到判决器，将信号与门限值0进行比较，确定传送的数据为+1还是-1，计数器用来记录判决器的错判数目。(According to the principle, first some straight expansion random number generator produces a series of binary data (+ 1-1), each information bit repetitive Lc times, Lc for each information bit contains PN code piece count, embraces each bit Lc times repeated sequence and another random number generator produces PN sequence c (n) multiplication. Then in the sequence superimposed on gaussian white noise and forms as I (n) = Acosw0n cosine interference next time signal, cut cosine interfering signal amplitude satisfy conditions A < Lc. In the modem with the cross-correlation operation PN sequence, and the information will comprise the Lc a sample bits peace. The output of the adder judgment device, will signal to compare with threshold 0 data transmitted, determine for+ 1 or-1, counter is used to record the number victimised judgment. )

ofdm在瑞利信道的仿真程序还有snr，ber图形(ofdm simulation program in Rayleigh channel also snr, ber graphics)

三相桥双极性PWM控制Simulink仿真，叠加一些其他信号，另加一滤波器观看PWM经过低通滤波后的波形，适合电力电子初学者(Three-phase bridge bipolar PWM control Simulink simulation, superimposed a number of other signals, plus a watch PWM filter through after the low-pass wave filter for power electronics for beginners)

计算Born-Jordon时间频率分布，需要输入的参数包括信号、时间、时间和频率的平滑窗口等参数(Born-Jordon calculating time-frequency distribution of the input signals ,including signals, time, time and frequency parameters of the smoothing window and so on .)

这是用matlab显示K线图的源码,还没有很多的指标，可以继续完善(this is a matlab m file to express stock chart)

产生宽带QPSK信号，并通过rrc滤波，用于检验发射通路的EVM等指标(Produce wideband QPSK signals, and by rrc filter, used to test the emission path of EVM and other indicators)

毕设，圆拟合程序，使用最小二乘法。 输出圆心，半径。(Picasso, circle fitting procedures set, using least-square method. Output circle, radius.)
