Hi, need a help for solving my project work. I am not getting the matlab code on the following specifications. In my work is have to reduce the dynamic range and I have to use kalman filter algorithm for reducing noise in matlab . I am listing the program specifications below. Kindly help me with the matlab code . thank you in advance.
Problem:
Give an input signal=-40 dbm
Add noise signal= -40 dbm
Combined signal to noise level= -40+(-40)= -37 dbm
Again signal is added+ -40 dbm
Eliminate noise which is added earlier (i.e. -40 dbm)
Then effective signal will be = -40 dbm
New signal added =-40 dbm
Reduce both signal level to -45 dbm
Reduce existing noise by -5 db
Then effective noise power = -45 db
Signal power available = -45 db
Now increase the dynamic range from -40 db to -45 db
Now reduce 1 db noise= -46 db
Reduce signal by -1 db i.e. = -46 db
Now the effective dynamic range = 6 db
Use kalman filter algorithm to reduce noise from -40 db to -46 db
Please help me with this code. thank you in advance
