Adaptive Switched-Capacitor Filters Based on the LMS Algorithm
The implementation of adaptive FIR filters based on the LMS algorithm using SC circuits is described. The filters consist of the basic elements: delay element, summing circuit, integrator, and multiplier. In an error analysis, the influence of nonideal effects of SC networks on the behavior of a given filter is investigated. It is shown that the nonidealities in the FIR filter part of the circu...
متن کاملPerformance analysis of sign-sign algorithm for transversal adaptive filters
The sign-sign algorithm (SSA), which is obtained by clipping both the reference input and the estimation error of the least mean square (LMS) algorithm, is analysed for transversal adaptive filters with correlated Gaussian data. The analysis focuses on the expected behaviours of the filter coefficients and the mean square error of the filter. The previous analysis of this type for the SSA is ba...
متن کاملPlant identification via adaptive combination of transversal filters
For least mean-square (LMS) algorithm applications, it is important to improve the speed of convergence vs the residual error trade-off imposed by the selection of a certain value for the step size. In this paper, we propose to use a mixture approach, adaptively combining two independent LMS filters with large and small step sizes to obtain fast convergence with low misadjustment during station...
متن کاملAffine projection algorithm for oversampled subband adaptive filters
The performance of the Normalized Least Mean Square (NLMS) algorithm for adaptive filtering is dependent on the spectral flatness of the reference input. Thus, the standard NLMS algorithm does not perform well in Over-Sampled Subband Adaptive Filters (OS-SAFs) because colored subband signals are generated even for white input signals. Thus we propose the use of the Affine Projection Algorithm (...
متن کاملAlgorithm for Convergence Criteria Simulation on Lms Adaptive Filters
A standard algorithm for LMS-filter simulation, tested with several convergence criteria under system identification configuration is presented in this paper. Establishing a reliable convergence criterion is mandatory in order to properly design an LMS filter and so avoid instability problems that may arise if both quantization effects and interdependency relationship among learning curve behav...
