| Summary: | 碩士 === 國立雲林科技大學 === 電機工程系碩士班 === 97 === The MIMO-OFDM technique is a new generation’s wireless communication technique. It is also one of the popular research themes. In this study, the researcher analyzed the performance of signal detection scheme for MIMO-OFDM system combined with Mapping-interleave . The researcher used Trellis Coded Modulation (TCM) and Non-uniform QAM to achieve our Mapping-interleave Scheme. The researcher also used the turbo code to provide more flexibility and ability for error control purpose in wireless transmission. According to the turbo encoded data, the researcher mapped them into Non-uniform QAM and then combined with TCM. In signal detection scheme of the MIMO-OFDM system, this study was to analyze the performance of the MIMO-OFDM system in different signal detection technique, such as Zero-forcing、 V-blast、 QR-blast、 Maximum likelihood search.
The result of analysis showed that the lower Bit Error Rate (BER) was for best signal detection scheme in Mapping-interleave for MIMO-OFDM.
