This adaptive noise canceller is then useful for enhancing the S/N ratio of data collected from sensors (or sensor arrays) working in noisy environment, or dealing with potentially weak signals.

In LMS adaptive FIR filter, the filter coefficients are updated using the LMS algorithm to be described briefly in the next section. There are various ways the coefficients are updated, including ...

LMS algorithm computes the filter coefficients and PSO search the optimal step-size adaptively. Because step-size influences on the stability and performance, so it is necessary to apply method ...
