source code for the removal of motion artifact in ecg using adaptive removal technique

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. )

MATLAB structures provide a way to collect arrays of different types and sizes in a single array. The following codes show how this can be made for problem1.m. One of the most interesting features is that the argument passing to functions is simplified. MATLAB codes for Finite Element Analysis problem1.m antonio ferreira 2008

CTP protocol DOC for WSN

非持续性CAMA是一种冲突避免的CSMA协议，如果终端检测到信道状态空闲，则立即进行数据传输，而信道状态忙，则停止载波监听，并随机在等待一段时间后再进行载波监听。(Non-durable CAMA avoid CSMA protocol is a kind of conflict, if the end channel state idle, detected immediately for data transmission, the channel state is busy, stop the carrier sense, and random carrier sense of the reentry after waiting for a period of time. )

这是关于matilab的一百个实例非常实用，初学者可以多加以琢磨(This is about the matilab one hundred examples, very practical, beginners can try to consider )
