hi, guys
I'm just beginning to study some materials of adaptive filtering in order to find if any enhance can be made to improve the performance of a power line communicaiton receiver. I just think that adaptive filtering has a very attractive technique name in the application of noise filtering --- it is called "noise cancellation". However, I wonder how can a dynamic FIR filter can achieve better performance than a fixed and well-designed FIR filter in getting rid of the noise out of band, if the receiving signal is a well-known digital-modulated signal, such as BPSK? Does any proof can prove it?
But I think adaptive filtering must have some advantage because it is widely-used in modern communication devices as I know. So does anybody can explained it to me if it is really so useful?
Many many thanks!
Regards!~
