FDMA-TDMA-CDMA: An Introduction By Dr. Ernest Simo 2.0 FREQUENCY DIVISION MULTIPLE ACCESS In Frequency Division Multiple Access or FDMA strategies, the focus is on the Frequency dimension. Here, we divide the bandwidth (b) into N Narrowband frequency slices. So, several users are allowed to communicate similtaneously by assigning Narrowband frequency slices to the users: On a Dedicated or Pre-assigned basis where a fixed frequency slice is assigned to a designated user at all times. Examples of Dedicated FDMA applications include AM Radio, FM Radio and Television Broadcasts. On a Demand-Assigned Multiple Access (DAMA) basis where an available frequency slice, or Channel, is assigned to a designated user for one call or one transaction only. An example of DAMA FDMA applications is the Analog cellular system. FDMA-TDMA-CDMA: AN INTRODUCTION By Dr. Ernest Simo © 1999 DR. ERNEST SIMO - SPACE2000
