"This book is essentially a guided tour of the fundamental concepts in digital signal
processing (DSP) and analysis, in which the guide is not a theoretician of the
various algorithms involved, but a user of them; a scientist that early in her life
started studying these techniques to apply them in a proper and fruitful way in her
research work. Therefore the approach to the various topics is the approach of a
user, more concerned about the way to best exploit the possibilities they offer,
rather than their purely mathematical facets."

"This book contains interesting findings of some state-of-the-art research in the field of signal and image processing. It contains twenty one chapters covering a wide range of signal processing applications involving filtering, encoding, classification, segmentation, clustering, feature extraction, denoising, watermarking, object recognition, reconstruction and fractal analysis. Various types of signals including image, video, speech, non-speech audio, handwritten text, geometric diagram, ECG and EMG signals, MRI, PET and CT scan images, THz signals, solar wind speed signals (SWS) and photoplethysmogram (PPG) signals have been dealt with. It demonstrates how new paradigms of intelligent computing like quantum computing can be applied to process and analyze signals in a most precise and effective manner. Processing of high precision signals for real time target recognition by radar and processing of brain images, ECG and EMG signals that feature in this book have significant implications in defense mechanism and medical diagnosis. There are also applications of hybrid methods, algorithms and image filters which are proving to be better than the individual techniques or algorithms. Thus the present volume, enriched in depth and variety of techniques and algorithms concerning processing of various types of signals, is likely to be used as a compact yet handy reference for the young researchers, academicians and scientists working in the domain of signal and image processing and also to the post graduate students of computer science and information technology."

"Dalam penelitian ini dibuat perangkat lunak Prosesor DSP (Digital Signal Processing) jenis TMS320C54X untuk memproses kerja rangkaian CDMA (Code Division Multiple Access). Dengan menggunakan beberapa algoritma yaitu algoritma matematis dan algoritma table lookup diteliti algoritma manakah yang mempunyai waktu proses yang paling cepat serta algoritma manakah yang memerlukan memori yang paling kecil. Dari hasil pengamatan, Algoritma Matematis memerlukan waktu proses 20.62 milidetik, sedangkan algoritma table lookup memerlukan waktu proses 14.08 milidetik . Dari hasil pengamatan dengan menggunakan metode table lookup waktu proses CDMA lebih cepat dibandingkan dengan metode Algoritma Matematis karena dengan algoritma Matemtis terjadi proses pembulatan yang tidak sama untuk setiap data masukan. Waktu proses 14.03 milidetik masih dibawah waktu delay yang diizinkan yaitu 125 milidetik. Meskipun demikian waktu proses tersebut masih ditambah dengan waktu proses Error correction dan proses pengkompesan suara (ADPCM atau QCELP).

This research develops the software of DSP Processor type TMS320C54X for the CDMA circuitry. This research apply two algorithms namely Mathematic Algorithm and table lookup Algorithm. From both algorithms, the research examine what algorithm have the fasted processing time and the smallest memory occupation. From the examination results the Mathematic Algorithm have 20.62 milliseconds processing time and the Table lookup algorithm have 14.08 milliseconds processing time. The Table lookup algorithm have the fastest processing time because the Matematic algorithm need the rounding process of the fi gure. Eventhough such processing time is not exceed from the 125 millisecond of delay time, in real condition, the total processing time are include the error correction processing time and voice compression processing time such as ADPCM or QCELP voice compression techniques."
