OFDM stands for Orthogonal Frequency Division Multiplexing. It is a digital modulation technique used in telecommunications, particularly in wireless communication systems, that allows for the transmission of large amounts of data over a given bandwidth.
In OFDM, the available frequency band is divided into many narrowband subcarriers, each of which carries a small part of the data stream. These subcarriers are orthogonal to each other, meaning that they have no mutual interference, which enables the transmission of multiple signals simultaneously without causing interference.
OFDM is widely used in modern wireless communication systems, including Wi-Fi, digital television, and 4G and 5G cellular networks. It is well-suited for high-speed data transmission because it allows for efficient use of the available spectrum, reduces the effects of interference, and enables high levels of spectral efficiency.
OFDM also provides robustness against multipath fading and other forms of distortion that can occur during wireless transmission. This is because the subcarriers can be spaced closely together, allowing the receiver to recover the original signal even if some of the subcarriers are lost or corrupted during transmission.
