Noncoherent Multistage Space-Frequency Coded MIMO-OFDM
碩士 === 國立中央大學 === 通訊工程研究所 === 97 === In 2005, a noncoherent space-frequency coded MIMO-OFDM scheme was proposed. But its complexity is very high if the number of tones is not small. In this thesis, we modify this scheme by using multistage decoding. All tones are divided into several groups. In each...
