| Summary: | 碩士 === 大同大學 === 通訊工程研究所 === 93 === The kernel concept of the software defined radio (SDR) is to annul the mixers and to place analog-to-digital converters as near the antenna as possible [2]. The reason why is that we can implement the most SDR functionality to a programmable micro or signal processor. Bandpass sampling is a helpful method for direct digital downconversion without mixers. Although the bandpass sampling theory for single RF signal is well developed, however, for two or more RF signals is relatively immature. In this thesis, we derived the general equations which are related to the bandpass sampling of multiple single-side-band RF signals. This is good to design the program to compute. That is meeting the center idea behind the software radio architecture.
