Hi everyone ..

Well I m doing a project on UWB system analysis ..

As i dont know much about matlab .. I need some information ..

I have created a matrix which contains my transmitted signal ..

and also i have found the matrix of channel impulse response ..

now i want to convolve them .. i know there is a command in matlab conv(a,b)

but i dont know how to put this resulting vector after convolution into my
vector ..

I explain to you with an example ..

t=0:0.01e-009:6e-009 .. that is length(t)`1

my waveform is of 1.3 ns duration .. that is length(t)1

now i find impulse response h,which has a length of for example 2000.

and the last multipath component arrives at 100 ns ..

now when i will do conv(h,x) .. i will have a matrix of length 2000+131-1!30.

if i use the same 0.01ns sampling in t .. the last value will be at 21.3ns

but in actual the last component arrives at 100ns ...

i m really confuse .. may be i m not clear in my dsp concepts ..

kindly anwer me if u know ..

Thanks

Rizwan
