DCA-Dynamical Channel Allocation

DCA-Dynamical Channel Allocation
Channel allocation in TD-SCDMA can be made very flexible due
to the use of synchronous TDD technology.

TD-SCDMA contains three different kinds of DCA:

Time DCA:The multiple Time Slots per carrier architecture can benefit each subscriber via selecting the least interfered Time Slot.

Frequency DCA:Frequency DCA will work by shifting serving channels to another less interfered carrier.

Space DCA: Adaptive smart antennas select the most favourable directional de-coupling between different users.

Dynamic channel allocation can decrease the interference, increase thecapacity.
