To achieve diversity with a single antenna, a fractional sampling (FS) scheme in OFDM has been proposed. FS achieves path diversity with a higher sampling rate and multiple demodulation branches. In the previous literatures for FS, the sampling interval is fixed even though the initial phase selection of the sampling has been investigated. The fixed sampling interval limits the diversity gain through...
MIMO-OFDM systems are expected to realize higher data rates and larger capacity. With more transmit and receive antennas the capacity of MIMO-OFDM systems increases. However, when the number of demodulators is limited, it is essential to select antenna points which achieve selection diversity. On the other hand, through Fractional Sampling (FS), it is possible to separate multipath components and...
