Hello.

i am looking for ways to improve SNR of a RFID signal that i have constructed in Matlab and mixed with a noise signal.
what ware there are to improve the SNR and what kind of filter i can use for this purpose.


thanks in advance
 

In your case first of you need to find out the noise that your are having have any specific range of the frequency, bandwidth......then you need to put corresponding type of filter - like band pass or band reject, filter order and filter component to achive that..... Matlab is just a simulation so you can choose the values of the components to first find out the transfer function of your filter....also in my view you also need to make sure that ripple response of the filter.....In my view you probably need a band pass filter and a simple way to desgin it keep a low pass and high pass filter in parallel with the corresponding cut of frequencies.....

Good Luck
 

can you give me a little help about the noise. what should i do on matlab .


regards
