Comparison Of Interpolation Methods In Modulation And Demodulation. Comparison of Interpolation Methods in Modulation and Demodulation

      Аннотация: 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.
