US Patent 10123212 DSA radio policy-controlled classifier restriction

A dynamic spectrum access (DSA) radio communication device includes a plurality of signal classifier modules operating thereon, with each different classifier module able to classify a different radio signal type. A classifier scheduler module is provided to manage classifier use by selecting which classifiers to operate or not to operate and to manage the order that the classifiers are operated in. The communication device is configured to invoke policies that include control elements associated with adjusting the classifier scheduler module. The control elements associated with adjusting the classifier scheduler module tend to reduce the number of classifier cycles required to classify a radio signal. The device includes or can be provided with a plurality of different policies suitable for different radio environments and operating modes. Specifically, different policies may include different classifier control elements suitably matched to the present radio environment and/or operating mode.
