One of the efficient ways to transmit high data rate is by employing a multiple-input multiple-output (MIMO) transmission. One\r\nof the MIMO schemes, known as spatialmultiplexing (SM), relies on the linear independence data streams from different transmit\r\nantennas to exploit the capacity from the fading channels. Consequently, SM suffers from the effect of spatial correlation which is\r\nthe limiting factor in achieving the capacity benefit that SM can offer. In an attempt to increase the robustness of the SM transmission\r\nin a wide range of correlated channels, the use of dynamic subcarrier allocation (DSA) is investigated. The effective signalto-\r\ninterference-and-noise ratio (SINR) metric is used as the performance metric to determine the subcarrier quality which can\r\nthen be utilised in the allocation. Two novel variants of the subcarrier allocation scheme are proposed. It is shown that the DSASINR\r\napproach improves the BER performance of SM transmission in highly correlated channels environment.
