10 Questions
1
The term narrowband is used to relate the bandwidth of a single channel to the expected coherence bandwidth of the channel.
2
In a narrowband multiple access system, the available radio spectrum is divided into a large number of narrowband channels.
3
In narrowband FDMA, a user is assigned a particular channel which is not shared by other users in the vicinity, and if FDD is used (that is, each channel has a forward and reverse link), then the system is called FDMAIFDD.
4
Narrowband TDMA, on the other hand, allows users to share the same channel but allocates a unique time slot to each user in a cyclical fashion on the channel, thus separating a small number of users in time on a single channel.
5
For narrowband TDMA, there generally are a large number of channels allocated using either FDD or TDD, and each channel is shared using TDMA.
In narrowband FDMA, how are channels allocated?
Each user is assigned a particular channel not shared by other users
What characterizes narrowband TDMA?
Users share the same channel but are allocated unique time slots
What is the key feature of narrowband multiple access systems?
The available radio spectrum is divided into a large number of narrowband channels
What distinguishes narrowband FDMA from narrowband TDMA?
Each user is assigned a particular channel not shared by other users in the vicinity (FDMA), while users share the same channel but are allocated unique time slots (TDMA)
What does narrowband TDMA generally involve?
A large number of channels allocated using either FDD or TDD, and each channel is shared using TDMA
Test your knowledge about narrowband multiple access systems, where the available radio spectrum is divided into a large number of narrowband channels and operated using FDD. Learn about minimizing interference and frequency split within the frequency spectrum.
