OFDM stands for Orthogonal Frequency Division Multiplexing. In OFDM, a single high-speed data stream is divided into multiple lower-speed subcarriers. These subcarriers are orthogonal to each other, meaning they do not interfere with each other. Each subcarrier is then modulated with its own unique signal and transmitted simultaneously. This allows for more efficient use of the available bandwidth and greater resilience to interference.
