Orthogonal Frequency Division Multiplexing (OFDM) is another widely used modulation method used to achieve high data rates and spectral efficiency . It is known as a multicarrier modulation method as many carriers are used instead of just one.
Read moreIs OFDM a modulation?
OFDM in its primary form is considered as a digital modulation technique , and not a multi-user channel access method, since it is used for transferring one bit stream over one communication channel using one sequence of OFDM symbols.
Read moreWhy OFDM is used in 4G?
Using multiple carriers, each carrying a low data rate, OFDM is ideal for high speed data transmission because it provides resilience against narrow band fading that occurs as a result of reflections and the general propagation properties at these frequencies .
