polynomial
Least-square curve fitting using polynomials is probably the most basic way to perform some parametric regression analysis. Foor basic tools for polynomial curve fitting are provided here. I also strongly recommend the exhaustive function POLYFITN

GAPSO-share
在做优化的时候,起初选择了GA算法,但是GA的不稳定性(或者陷入局部最优)实在让人抓狂,前后两次的结果相差竟然有时候能达到30 以上,当时由于时间的原因,我只好选择了优化1000次,然后以其中的最小值最为最佳方案。虽然问题也算解决了,但是从学术上将,这种奔方法是让人很尴尬的。所以,我从网上下载了一个GA-PSO算法,试着利用GA和PSO组合的策略进行优化,结果算法很问题,效率和不错。我下载原始算法,有一个问题就是它是针对所有的设计变量上下限都是一样的,所以我对程序进行了修改与改进,现在可以处理上下限不一致的问题,同时fix了一些bug。现在把修改后的程序和大家分享一下,希望能对您有用.注意myfit需要用自己的函数,否则出错,因为我的myfit程序在调用过程中,需要使用matlab的Kriging工具箱

ofdm
说明: 该项目用于通过使用导频序列(训练序列)和信道抽头来估计OFDM中存在的信道。使用BER曲线比较系统的性能,该BER曲线是针对均匀间隔的飞行员和紧密间隔的飞行员获得的。此外,通道抽头的数量也有所不同,以估算最佳的BER曲线(This project is used to estimate the channel in OFDM by using pilot sequence (training sequence) and channel tap. The BER curve is used to compare the performance of the system, which is obtained for pilots with uniform interval and pilots with tight interval. In addition, the number of channel taps varies to estimate the best BER curve)
