janu203 said:Is vector OFDM (Orthogonal Frequency division multiplexing) same as MIMO?
What are vector blocks in a MIMO system then?
I know what is Frequency division multiplexing but can't understand orthogonal FDM.
HELP!

MIMO stands for Multiple-Input Multiple-Output and refers to a wireless communication technique that uses multiple antennas at both the transmitter and receiver to improve data transmission.
Vector OFDM stands for Vector Orthogonal Frequency Division Multiplexing and is a wireless communication technique that uses multiple antennas and subcarriers to improve data transmission.
The main difference between MIMO and Vector OFDM is that MIMO uses multiple antennas to transmit and receive data, while Vector OFDM uses multiple antennas and subcarriers. MIMO is also typically used in point-to-point communication, while Vector OFDM is used in multi-user systems.
Both MIMO and Vector OFDM have their own advantages and are used in different scenarios. MIMO is better for point-to-point communication and can provide higher data rates, while Vector OFDM is better for multi-user systems and can provide better coverage and reliability. Therefore, the choice depends on the specific needs of the wireless communication system.
One potential drawback of MIMO is that it requires precise synchronization between the multiple antennas, which can be challenging in some scenarios. On the other hand, Vector OFDM can be more susceptible to interference and requires more complex signal processing techniques. However, both techniques have been extensively researched and optimized to minimize these drawbacks.
