hi,
i have formulated extended kalman filter estimation for a channel with sine wave input. now i want to make the channel rayleigh faded. i need the slow fading case. can anyone please help me with it...
Thank you..
Hi sabin14,
I think the problem is with the value -0.8735. I checked and every time, i am getting the same value. But the 'if' loop is not working. I can't figure out what mistake i made in this. Anyway, i used another criteria. Thank you.
Hi,
I would like to know the applications of kalman filtering and EKF in satellite and mobile communication in detail...can anyone have any idea about it..please suggest any books or webpage for the same...
Thank you...
Hi all,
Any suggestions for the modifications possible please?...
This is the code i am using..
Also please make me know if any mistakes are there in the code..
clc;
clear all;
close all;
N = 20;
W = [ 0 0 ; 0 1 ]; % State-error
V = [ 1 0 ; 1 2 ]; % Measurement-error
H = [ 3 2 ; 0 0 ]; %...
Hi all,
I am doing a project on extended kalman filter estimation...and i am using sine wave as the input for the same..until now, i have found the predicted estimates and the updated estimates....then i have calculated the error by calculating the difference between these two estimates and...
Hi arunava7,
Can you please check whether this code will be enough to find the THD using your suggestion..?
XX1 = abs(fft(aposteriori_state)).^2;
% to find the maximum signal power
XX2 = sort(XX1);
power = find(XX1(1:700)==XX2(700));
signal_power = XX1(power)
harmonic_power =...
Also how should i find the frequency and power of these sine waves to calculate the THD in the way as you suggested..?
Please do reply.....It is somewhat urgent.....
Thank you....
Hi arunava7,
This is the code i am using..While plotting apriori_state and aposteriori_state, i am getting sine waves which are distorted..The distortion of that waveform needs to be calculated..I dont have any other information about the waves,, naa..Then how can i find the amount of...
Is there any method for calculating the distortion of a sine wave,, in matlab....?
When i did extended kalman filter estimation with input as sine wave, i got the predicted and updated output sine waves as distorted..and i would like to find the amount of distortion to limit the output...So...
extended kalman filter estimation
Hi all,,
What is the difference between kalman filtering and extended kalman filtering channel estimation...can nyone tel how they differ in their equations..i would also like to know the differences in formulating matlab codes for them...for sinusoidal...
I am doing channel estimation using extended kalman filter for a sine wave input..this is the code i obtained..can anyone suggest whether any modifications or corrections are required....
I got the parameters from internet and so i am not familiar about why these values are used...can u please...
