What does the MIMO in MIMO-OFDM stand for?

MIMO in MIMO-OFDM stands for Multiple Input, Multiple Output. This technology is integral to modern wireless communications, particularly in increasing the capacity and efficiency of data transmission. By using multiple antennas at both the transmitter and receiver ends, MIMO can transmit and receive more than one data signal simultaneously over the same radio channel.

This capability enhances the throughput and reliability of wireless networks, making it particularly beneficial for technologies that require high data rates, such as Wi-Fi, LTE, and 5G. MIMO operates within the context of Orthogonal Frequency Division Multiplexing (OFDM), which further improves performance by dividing the wireless signal into multiple sub-signals that can be transmitted simultaneously, minimizing interference and maximizing the use of available bandwidth.

The other options do not reflect established terminologies within the communications discipline, which is why they do not apply to MIMO-OFDM.
