The various components of the UE 1802 are coupled together by a bus system 1811, which may include a power bus, a control signal bus and a status signal bus, in addition to a data bus. However, for the sake of clarity, the various buses are illustrated in FIG. 16 as the bus system 1811. The UE 1802 may also include a digital signal processor (DSP) 1813 for use in processing signals. The UE 1802 may also include a communications interface 1815 that provides user access to the functions of the UE 1802. The UE 1802 illustrated in FIG. 16 is a functional block diagram rather than a listing of specific components.
