Abstract

There is a significant demand for a decrease in the size, weight and power (SWaP) associated with wireless systems. In recent years, multiple-input, multiple-output (MIMO) wireless systems have received considerable attention due to the high data rates they provide. Orthogonal frequency division multiplexing (OFDM), a digital multi-carrier modulation technique, is well suited to be used in MIMO systems as it provides the ability to operate in frequency-selective channel environments. When OFDM is combined with the channel capacity increase provided by MIMO systems, the result is a very successful communication system. In this research, a low-complexity MIMO OFDM system is advanced. The proposed system is essentially multiplierless and thus requires much simpler digital hardware to be implemented. As a result, the chip area associated with the MIMO OFDM system can be significantly reduced.
