Detailed explanation-1: -FDMA (Frequency Division Multiple Access) TDMA (Time Division Multiple Access) CDMA (Code Division Multiple Access)
Detailed explanation-2: -Time Division Multiple Access (TDMA) is a digital modulation technique used in digital cellular telephone and mobile radio communication. TDMA is one of two ways to divide the limited spectrum available over a radio frequency (RF) cellular channel. The other is known as frequency division multiple access (FDMA).
Detailed explanation-3: -FDMA only requires the guard bands between adjacent channels, whereas TDMA requires the guard time of the adjacent slots. On the other hand, CDMA requires both guard time and guard bands. FDAM has a low data rate, whereas TDMA has a medium data rate. On the other hand, CDMA has a high data rate.
