Moreover, to increase OFDM systems capacity, the use of antenna arrays within the MIMO systems needs particular attention for channel estimation purposes. Since the efficiency and performance of a ...

MIMO-OFDM Multiple-input, multiple-output (MIMO) technology allows a wireless access point (AP) to work with up to four separate data streams simultaneously. 802.11ax brings MIMO with orthogonal ...

MIMO takes four independent OFDM carriers, and puts them on top of each other, so really you have four separate transmissions, all sharing the same frequency. You can either carry more information in ...

In this paper, a Fast Fourier Transform (FFT) or inverse FFT processor for Fifth-Generation (5G) Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) system’s ...
