Simplified channel equalization and reduced complexity

[bitheerani93]

While OFDM's tolerance to channel imperfections is impressive, its ability to simplify channel equalization and reduce overall system complexity is a very important advantage in digital communications.

OFDM's simplified equalization is achieved by transmitting data over subcarriers, eliminating the need for complex spain mobile database in the time domain. This reduced complexity is noticeable compared to single-carrier systems:

nature OFDM Single carrier system
Equalizer type Frequency domain Time domain
Complexity low high
Computational burden reduce intense

OFDM Applications and Uses

OFDM technology has been widely used in various communication fields, demonstrating its versatility and efficiency.

In wireless networks, OFDM is a key component of 4G and 5G cellular systems, including the Wi-Fi protocol, enabling high-speed data transmission and efficient use of spectrum.

Its resistance to multipath fading and interference makes OFDM used in digital audio and video broadcasting for television and voice systems, while its ability to maximize bandwidth makes it valuable in wired communications infrastructures such as DSL and powerline networks.
