Adaptive Antenna is one of the hottest research areas.
There is not single algorithm or techniques that can
cope with all different propagation environments.
A software antenna has been proposed to provide an
effective means to cope with changes in the surrounding environment,
#by combination of different techniques such as beam forming,
equalizers and adaptive algorithms.
Recently blind algorithms
(where there is no need for reference signals) have been
incorporated within these techniques specially to
improve overall system capacity.
The aim of this project is to implement a blind
re-configurable Adaptive antenna system, which will consist of beam
formers and equalizers and varieties of Constant Modulus
algorithms, where combinations of different CM algorithms can
be used to mitigate different changes in the environment.
A simple architecture of a proposed system is shown below.
Each different algorithm has its own unique performance.
In different environments by having more than one specific
algorithm gives the base station move flexibility and the advantage
of best performance for each situation. These types of systems
are more complex to implement than conventional ways but
once the main platform of the system is implemented it can
be very easily maintained when new algorithms are.
