This paper investigates the researches was done on the TI-ADC considering various problems specially the mismatches occur in during conversion. As we studied, the main reason of these mismatches is the non-uniform manufacturing of the TI-ADC ICs, and due to these reasons mismatches in the form of time, frequency, offset and gain introduced in the signals during conversion process. Many research...

Application of the filtered-X LMS algorithm to adaptive/active noise cancelling in headsets or hearing protectors has been investigated. The speed of convergence and amount of obtainable noise reduction was investigated for different step-size parameters and FIR filter lengths. Simple models for the headphone transfer function and the sound transmission through the ear cups are applied. We have...

This paper presents an H, estimation approach to active control of acoustic noise inside an enclosure. It is shown how Hfilter theory and algorithm can be effectively applied to active noise control to provide important robustness property. Real-time implementation of the algorithm is performed on Digital Signal Processor. Experimental comparison to conventional FxLMS algorithm for active noise...

Gain and timing mismatches in a time-interleaved analog-todigital converter (TI-ADC) cause spurious images in its output spectrum thus effecting its performance. In this paper. we present an efficient digital blind identification structure to adaptively estimate gain and timing mismatches by using the filtered-error least-mean square (FxLMS) algorithm. The identification of mismatches helps in ...

This report presents about the comparison of the performance among four different adaptive algorithms for suppressing impulsive noise. They are filtered-x least mean square (FXLMS) algorithm, least mean M-estimate (LMM) algorithm, filtered-x least mean M-estimate (FXLMM) algorithm, and a modified FXLMM algorithm. A designed noise, which is composed of impulsive noise and background noise, is us...
