Abstract

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 obtain diversity gain. Just like MIMO systems, FS achieves selection diversity by selecting sampling points. This paper presents an antenna/sampling point selection algorithm for MIMO-OFDM systems with Fractional Sampling. Utilizing the characteristics of the correlation among the sampling points in FS, the proposed selection algorithm offers significantly lower computational complexity than conventional algorithms. The proposed algorithm is confirmed through the computational simulations.
