Abstract:

Diploma thesis deals with design of verification environment for analyzing systems with digital filters. Verification environment is written in SystemVerilog language and it is generated by program, which is also providing generation of input data for system of filters. Matlab environment is used for gaining the reference data. The simulation of the designed involvement with digital filters is performed by program ModelSim. The most watched parameter is functional coverage which indicates how big part of the HDL description has been tested.

Abstract:

Adaptive filtering techniques are used in a wide range of applications, including echo cancellation, adaptive equalization, adaptive noise cancellation, and adaptive beamforming. The performance of an adaptive filtering algorithm is evaluated based on its convergence rate, misadjustment, computational requirements, and numerical robustness. We attempt to improve the performance by developing new adaptation algorithms and by using "unconventional" structures for adaptive filters.

In this thesis, we considered the deconvolution problem when the channel is known a priori. LSE and MSE optimum solutions are investigated with deterministic and statistical approaches. We derived closed form LSE expressions and investigated the factors that affect the FIR inverse filters. It turns out that, minimum LSE can be obtained when the system zeros are distributed homogeneously on the z-plane. We proposed partition-based FIR-IIR inverse filters. The selection of FIR and IIR parts is based on partitioning the channel zeros into two regions and using the specified channel zeros to desig

Abstract:

Conventional methods of CFAR detection always use windowing, in the sense that some number of cells are investigated and the target present/absent decision is made according to the composition of the cells in that window. The most commonly used versions of CFAR detection algorithms are cell averaging CFAR, smallest of cell averaging CFAR, greatest of cell averaging CFAR and order-statistics CFAR. These methods all use windowing to set the decision threshold. In this thesis, rather than using windowed CFAR algorithms, a new method of estimating the background threshold is presented, analyzed an

In automatic speech recognition systems (ASRs), training is a critical phase to the system?s success. Communication media, either analog (such as analog landline phones) or digital (VoIP) distort the speaker?s speech signal often in very complex ways: linear distortion occurs in all channels, either in the magnitude or phase spectrum. Non-linear but time-invariant distortion will always appear in all real systems. In digital systems we also have network effects which will produce packet losses and delays and repeated packets. Finally, one cannot really assert what path a signal will take, and

Abstract:

碩士<br>樹德科技大學<br>電腦與通訊研究所<br>97<br>This thesis applies an optimal algorithm called real-coded genetic algorithm (RGA) to the design of digital infinite impulse response (IIR) filter. The RGA used is quite different from the traditional binary-coded algorithm (BGA) because the optimized variables are directly in the form of real numbers. It is more convenient and efficient in solving the physical engineering optimization problem. To evaluate the performance of each chromosome, the mean squared error (MSE) is taken as the system’s error function. Moreover, for dealing with more complicated pr

Owing to human sense, like sense of hearing , sense of sight, is not uniformly distributed in frequency, Non-uniform Division Filter banks is even more important than QMF in some aspects. In this thesis, we focus on both structure of filter banks. CORDIC algorithm is an approach to perform angle quantization. It can quantize coefficients in angle space which is denser than coefficient space. Besides, coefficients quantized by CORDIC algori

The work of this thesis is to devise novel and efficient techniques for optimally designing digital filters and QMF banks based on IIR all-pass filters. With the aid of WLS and Karmarkar’s algorithms, several minimax design methods are proposed.

碩士<br>國立交通大學<br>電子研究所<br>106<br>The target of this Thesis is to develop a high charger noise immunity analog front-end circuit for touch sensing, which can be applied in the consumer electronics products. Its transmitter employs parallel driving by code-division sensing method. It senses the projected capacitive change. In the receiver, it can be divided into two part. In front part, we use current conveyor to transform the information of capacitance to current signal, and do the adjustment for signal amplification and capacitance baseline removal. It also avoids to use large feedback capacito
