Re: Volterra Series
Dear qiushidaren,
Volterra Series is a Taylor series with memory (Schetzen). You can use Volterra for continuous time signals as well as for discrete time signals. It can be used in time domain and frequency domain. Volterra Series can be used to represent Wiener, Hammerstein and Wiener-Hammerstein blocks.
Its applications are in Communications (sattellite channel, Linear filter in cascade with power amplifier), where it can be used for identification, predistortion and equalization. In biomedical engineering, Echo cancellation, OFDM sytems, analog to digital converters ....to mainly linearize and improve their performance.
Hope this little helps......
