dear all

please help me to solve matlab codes which are attached here the codes are of evaluation of wimax/ieee 20816 ofdm physical layer.

one attached file a.m contain whole code while other contain Tx.m, Rx.m, chenel_Sui.m which are parts of whole code.

please solve all error and make it runable.

i use matlab 2007b

thanking you in anticipation

I think this my post can you provide little bit help.I want Solve below differential equation by ODE 45,
%y"1+y1-y"2-4y2=0
%y'1+y'1=cos(t)+2cos(2t)
%y1(0)=0, y'1(0)=1, y2(0)=0, y'2(0)=2,
%ans y1=sin(t), y2=sin(2t)
I write this below cod in Matlab but it is Wrong. Please help me.

function dy=ssin(t,y)
dy=zeros(4,1);
dy(1)=y(3);
y(2)=y(4);
dy(1)=-dy(2)+cos(t)+2*cos(2*t);
dy(3)=-y(1)+dy(4)+4*y(2);
