In the proposed scheme, each UT feeds back its CSI to all collaborative BSs, and the needed operations of user scheduling and signal processing are performed in a distributed fashion.
Each MS feeds back its CSI to all collaborating BSs, and the needed operations of user scheduling and signal processing are performed in a distributed fashion by the involved BSs.
Moreover, IC-Agents are capable of monitoring and logging all the operations of user (for instance authorizations and other service accesses), which may help to carry out the auditing processes as per SP's requirement, thus offering support to Auditing and Logging principle.
We, therefore, use Chado for read operations of data residing in the data warehouse, but opted to create a Chado schema within Drupal for read/write operations of user-contributed data.
In order to access available spectrums, secondary users have to detect the vacant spectrum resources by themselves without changing the operations of primary users.
Techniques like deep neural networks Bengio (2009) integrate several context information such as operation histories of users.
An online learning algorithm is then presented that is able to learn preferred parameter values from control operations of a user during usage.
In cognitive radio networks, secondary users are allowed to opportunistically access spectrums which have already been allocated to primary users, given that they do not cause harmful interference to the operation of primary users.
That is, one extra network-coded operation of both users' messages is not always necessary by the cooperative scheme of [7] in moderate-to-high SNR regime.
Cognitive radio techniques are majorly studied and practiced for operation of secondary users in licensed bands while this framework focuses on deploying such techniques in the unlicensed ISM band.
