Multicarrier Modulation

Multicarrier modulation is a technique used in communication systems where a signal is divided into several smaller signals, each transmitted independently over different frequency bands called carriers. Think of it like splitting a large message into multiple smaller messages on different radio stations, then sending them all at once. When these signals reach the receiver, they are combined back into the original message. This approach improves data transmission efficiency and reliability, especially in complex environments like wireless networks. Popular forms include OFDM (Orthogonal Frequency-Division Multiplexing), which is widely used in Wi-Fi, LTE, and 5G networks.
