| Summary: | 碩士 === 國立中正大學 === 電機工程研究所 === 91 === In this thesis, we examine the properties of modulation signal constellation and then make use of these properties. By taking advantage of the properties among the modulation points, we design the orthogonal space-time codes and the corresponding generator matrix to produce those orthogonal codes. From simulation, we discover the orthogonal space-time codes found in this thesis are the kernel of discrete time Fourier transformation.
Based on the observation and signal design flow, we propose the two-stage configuration and the index matrix generator for the orthogonal space-time encoder. By this way, we can obtain the orthogonal space-time codes systematically.
