Prog_OFDM
应用OFDM可以有效地对抗多径时延扩展。循环前缀不仅可以消除符号间干扰(ISI),还能消除子载波间干扰(ICI).本项目完整地仿真了OFDM系统。(Application of OFDM can effectively combat multipath delay spread. Cyclic prefix can not only eliminate inter-symbol interference (ISI), can eliminate Inter-carrier interference (ICI). This project a complete simulation of the OFDM system.)

LeastSquare
this is matlab code for estimating the static linear system with Least Squre that is written by matlab 7.0.
Here we want to estimate the below function:
1 - u^2 + 2*u^3 +u^5 +3*u^7
these are 2 files : without noise and with noise
finally,there are plots for showing results.
