The filtered-x least mean square (FXLMS) algorithm is widely used for active noise control (ANC) systems. However, due to the fixed step-size of FXLMS algorithm being used, the FXLMS algorithm results in a compromise between noise reduction performance and convergence speed. Therefore, this ...
Further we work to modify these basic algorithms so as to obtain Normalized Least Mean Square algorithm, Fractional Least Mean Square algorithm, Differential Normalized Least Mean Square algorithm, Filtered-x Least Mean Square algorithm etc. In this paper we work to provide an improved approach for...
The dsp.FilteredXLMSFilter System object computes output, error and coefficients using filtered-x least mean square FIR adaptive filter.
An enhanced, frequency domain filtered-x least mean square (LMS) algorithm is proposed as the basis for an active control system for treating powertrain noise. There are primarily three advantages of this approach: (i) saving of computing time especially for long controller's filter length; (ii...
As the most commonly used active control algorithm, the filtered-x least mean square (FXLMS) algorithm plays an important role in active noise control (ANC) systems. The time domain FXLMS (TD-FXLMS) algorithm is known for its simplicity and robustness for both stationary and non-stationary nois...

While the least mean square (LMS) algorithm has been widely explored for some specific statistics of the driving process, an understanding of its behavior under general statistics has not been fully achieved. In this paper, the mean square convergence of
they can’t be targeted by opposing characters 5+ squares away.” This is the same thing as the “Behind the Scenes” trait from the XDPS, but it will protect your entire team. It’s also superior to what Prime Bishop can do because he lets opponents target from 1 square further away...
is the mean value of the Wigner distribution Wxx(t,f) of the signal x(t) (i.e., the Wigner spectrum [33] of x(t) (see Chapter 2, Section 2.2). We can conclude that Eq. (11.3.2) is of the same form as the Wienerfilter for the stationary case. If the signal and noise are...
Due to the size of fine bubbles, the mean surface area will be greater than that for coarse bubbles and the rate of ascent to the surface will be slower. Rise rate is a function of the square of the diameter. If the bubble diameter is reduced by a factor of 4, the rise rate is ...
