A proposal for source separation of ground borne vibration signals and its FPGA implementation

摘要

The source separation of low level ground borne vibration signals and its FPGA implementation is an exigent problem. This can be viewed as a complex version of the classical source separation problem, the `cocktail party problem'. An extension of the basic Independent Component Analysis (ICA), a Blind Source Separation method is proposed in this particular case, as the damping of the ground borne vibration signals is significant. The separation of a set of signals from a set of observed signal mixtures, without the information about the source signals or the mixing process is known as Blind Source Separation (BSS). Field Programmable Gate Arrays (FPGA) are increasingly used various fields from audio to wireless communication. A suggested model for source separation of ground borne vibration on FPGA is discussed in this paper.
