A Rate-one Full-diversity Low-complexity Space-Time-Frequency Block Code (STFBC) for 4-Tx MIMO-OFDM

Many papers have extended STBC design to frequency-selective channels. In [6], STBC has been proposed for single-carrier transmission, which can achieve maximum space-delay diversity in rich scattering channels. The transmission formats proposed

Multiple antenna (MIMO) devices are widely used to increase reliability and information bit rate. Optimal error rate performance (full diversity and large coding gain), for unknown channel state information at the transmitter and for maximal rate, ca
