Alsalam alikom

i need to know how to make a matlab code for LMMSE channel estimation, provided that i use matlab built-in rayleihchan command

also i need help in this topic https://www.edaboard.com/threads/211733/

and finally i want to know how to use a interpolation filter optimized according to the Wiener filter theory
thanks very much in advance
:-D:-D

Are you sure you have to use a wiener filter ?
Wiener filter is the optimum solution for 2D channel estimation via interpolation, but you can replace it with successive 1D interpolations once in the frequency domain and once in the time domain. 2D wiener filtering is way more complex without much performance gain.
 
thanks for ur help
ok i want to know how to use 1D wiener filter for channel estimation??

is there any paper or any tutorial that can help me for that ?? espically i wan to use it in matlab simulation

Ramadan kareem for u
 

Allahu Akram :)

Re: need help in wiener interpolation

I want to calculate coeffient wiener filtering for ofdm.This is production of cross-correlation and auto-correlation.
the matrix of wiener filtering is apply for channel estimation of rectangular pilot grid.
can You help me calculate this matrix?
Thanh you!
:sad:
