OFDM

Orthogonal Frequency Division Multiplexing (OFDM) is a technology used in modern wireless communications to transmit data efficiently and reliably. It works by splitting a data stream into many smaller, parallel signals, each carried on its own narrow frequency band called a subcarrier. These subcarriers are carefully timed so they do not interfere with each other, allowing for high-speed data transfer even in challenging environments like urban areas or indoors. This method improves bandwidth usage and reduces susceptibility to signal noise and interference, making it ideal for systems like Wi-Fi, LTE, and digital broadcasting.
