The direction of target is sent and received signal, so inevitably interference is produced to the direction of non-targeted, therefore can not be abundant
Using existing frequency spectrum resource.When sharing frequency spectrum with authorized user (PU), reduce the interference that unauthorized user (SU) produces, energy
Make SU and PU shared channel, steerable antenna technology can be incorporated in cognitive radio system.Unauthorized user (SU) uses
Steerable antenna is launched and is received, when unauthorized user (SU) is in emission state, by the user's shape to unexpected direction
Become null, make the user of desired orientation receive signal to noise ratio maximum；When unauthorized user (SU) is in reception state, only in expectation
Receipt signal on direction, the signal beyond null narrow-band beam；So both can avoid unauthorized user (SU) to authorized user
(PU) produce interference, and interfering and between other user can be reduced.Steerable antenna is to be realized by space division multiple access principle
Differentiation to different user, thus improving the availability of frequency spectrum and communication quality, improves the performance of cognitive radio system.
The structure of steerable antenna is mainly made up of following four part：Aerial array, analog digital conversion (A/D), Wave beam forming
Network, self-adaptive processing part.

Cloth linear array, cross battle array etc..
(2) analog digital conversion part：Receives link (descending) by analogue signal conversion digital signal, transmitting chain (up) by
Digital signal converting analogue signals.
(3) self-adaptive processing part：By adaptive algorithm and digital signal processor come to the signal of real-time input and
Interference vector is processed, for producing adaptive best initial weights parameter.
(4) beam-forming network：Dynamic self-adapting weighting can process, process through adaptive signal processor, produce
Desired adaptive beam.
In cognitive radio system, aerial array just can not adjust after setting, and so can affect the performance of system.
