Adaptive filter - Wikipedia

An adaptive filter is a system with a linear filter that has a transfer function controlled by variable parameters and a means to adjust those parameters according to an optimization algorithm. Because of the complexity of the optimization algorithms, almost all adaptive filters are digital filters. Adaptive filters are required for some applications because some parameters of the desired processing operation for instance, the locations of reflective surfaces in a reverberant space are not known in advance or are changing. The closed loop adaptive filter uses feedback in the form of an error signal to refine its transfer function. Generally speaking, the closed loop adaptive process involves the use of a cost function , which is a criterion for optimum performance of the filter, to feed an algorithm, which determines how to modify filter transfer function to minimize the cost on the next iteration. The most common cost function is the mean square of the error signal.

Here are the instructions how to enable JavaScript in your web browser. Thus the variance of Rx e j is further reduced while broadening frequency peaks or decreasing resolution.

Then use it to factorize the matrix in Example 6. An LMS-type algorithm is obtained by using the instantaneous gradient. To reduce the amount of interference in the primary microphone, a second microphone is located where it is intended to pick up sounds from the engine. Visually, the trace has self repeating but increasing structures.

The code is broken up into parts ab and c and presented sequentially along with the accompanying gures. Poluektov and A. The most common cost function is the mean square of the error signal. Note that the magnitude response of the lter is the inverse of the channel.

Aims and Objectives: This course examines the fundamentals of detection and estimation for signal processing. It will help the students to implement new algorithms for signal processing applications in the frequency and time domains. Course Outcome: Students will learn to design a filter by properly estimating the spectrum for the signal when it is deterministic or random in nature. Parameter estimation using Yule-Walker method. Tools and aids for firmware development, typical implementation of DSP algorithms. Monson H. John G.
