Adaptive baseband sub-system for TRUST

A novel software architecture of the baseband sub-system for a software defined radio terminal is presented. The architecture is flexible, such that it can re-configure itself upon the availability of appropriate software. An object-oriented approach is considered, whereby the functionality of a given baseband module can be changed by instantiating appropriate classes. The formulation of baseband classes and their associated attributes is considered. A management entity is assumed to regulate, administer and manage baseband re-configuration. The functionality of this entity, together with the signalling required to perform re-configuration is also described. Whilst this flexible architecture is restricted in its scope to the baseband sub-system, it is conceptually suitable for re-configurable higher layers as well, assuming a conventional modular protocol stack
