Following are the difference between FDMA (frequency division multiple access) and TDMA (time division multiple access) :
|FDMA stand for frequency division multiple access.
||TDMA stand for time division multiple access.
|The FDMA (frequency division multiple access) is not required synchronization.
||It is required synchronization.
|It has less power efficiency.
||It has more power efficiency.
|It requires high carrier frequency stability.
||The high carrier frequency is not necessary.
|It has divide frequency band into disjoint subband.
||It has divided the time into non overlapping time slot.
|Its Entire band of frequencies is divided into multiple RF channels/carriers. Each carrier is allocated to different users.
||Its entire bandwidth is shared among different subscribers at fixed predetermined or dynamically assigned time intervals/slots.
|It has continuous transmission scheme.
||It discontinuous transmission scheme.
|It used in GSM and PDC.
||It is used in advanced mobile phone systems (AMPS).
