Comparison of Interpolation Methods in Modulation and Demodulation: Comparison of Interpolation Methods in Modulation and Demodulation Hiba Haidar

The purpose of this book is to contribute to Signal Processing through researching, testing, and evaluating of the best method to interpolate a signal?s sample frequency at the modulator of an acoustic modem and a matching decimation method at the de-modulator end, where the result is the original signal. This research of this problem and results were published as a thesis to earn a Master?s Degree in Electrical Engineering from San Diego State University under the supervision of Professor fred j. harris Ph. D. This book can serve as a simplified way to understand concepts of signal processing in particular several ways of up-sampling and down-sampling such as: Brute Force, Half-Band Filters, and Polyphase Filters. Numerical examples and Matlab Code implementations are provided to enhance the understanding of concepts presented in this book.
