Description: 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 in [6] subsume
those of [7], [8], which present time-reversal STBC at the transmitter
to achieve transmit diversity. Multicarrier transmission systems have
been considered in [9]–[11]. A space–time–multipath coded system is
developed in [12] using digital phase sweeping (DPS) in the frequency
domain or circular delaying in the time domain, which guarantees
the maximum possible space-delay diversity, and has full rate for any
number of transmit–receive antennas. Note that the aforementioned
algorithms all require the channel to be constant over the entire

Description: 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, can be achieved by approximately universal space-time codes Platform: |
