What is the significance of MIMO OFDM?

Orthogonal frequency division multiplexing (OFDM), known for its robustness against multipath fading, is the modulation technique employed to circumvent the hazardous effects of intersymbol interference (ISI). MIMO is the key technology for achieving capacity advantage and improving link reliability.

Is OFDM used in MIMO?

MIMO-OFDM is also used in the 802.11ac standard and is expected to play a major role in 802.11ax and fifth generation (5G) mobile phone systems. Several early papers on multi-user MIMO were authored by Ross Murch et al.

How are higher spectral efficiency and increased throughput achieved in the OFDM MIMO system for 3g & 4g network?

By increasing the number of receive and transmit antennas it is possible to linearly increase the throughput of the channel with every pair of antennas added to the system (Figure -2). This makes MIMO wireless technology one of the most important wireless techniques to be employed in recent years.

Is OFDM a modulation technique?

Orthogonal frequency division multiplexing (OFDM) is a modulation technique that is used in several applications ranging from cellular systems (3GLTE, WiMAX), wireless local area networks (LANs), digital audio radio, underwater communications, and even optical light modulation.
