Sampling Frequencies Ratio Estimation And Symbol Timing Recovery For Baseband Binary Pulse Amplitude Modulation, Ana A. Paniagua Rodriguez
Sampling Frequencies Ratio Estimation And Symbol Timing Recovery For Baseband Binary Pulse Amplitude Modulation, Ana A. Paniagua Rodriguez
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The original intent of this project was to perform real time digital communications between a personal computer (PC) as the transmitter and a digital signal processor (DSP) as the receiver using the audio band analog channel. Although transmitter and receiver were both designed with baseband binary Pulse Amplitude Modulation (PAM), a low data rate and a sampling rate of 8 kilohertz, it was not possible to achieve communication between the two with traditional synchronization algorithms because of large differences in sampling clock frequencies. This thesis explores the theory and results of implementing digital communications between systems with differenet sampling frequencies. …
