An apparatus comprising at least two controllers each providing control information for controlling phase or frequency of a digital signal, a combiner for combining control information from the at least two controllers to combined control information and a phase rotator for adjusting, by using phase rotation, one or more of the phase and the frequency of the digital signal on the basis of the combined control information.

Apparatus and method to adjust a phase and frequency of a digital signal

The present invention provides methods and apparatuses for utilizing unused portions of an allocated frequency spectrum in a wireless communications system that broadcasts content to wireless stations. A first wireless station may communicate with a second wireless station on an idle broadcast channel while keeping the resulting interference level below an acceptable maximum limit at the other wireless stations. Using interference level information that are measured at the wireless stations, the wireless station can negotiate with the other wireless station on an establishment channel for subsequent communications on one or more broadcast channels. The wireless station may receive broadcast content on a time slice that corresponds to a broadcast channel and that is further processed by the wireless station. Otherwise, the wireless station can utilize the corresponding time to measure an interference level for the corresponding channel or to transmit or receive data to/from another wireless station.

System and method utilizing a cognitive transceiver for ad hoc networking

The disclosure details the implementation of an apparatus, method, and system for an network selector for datacasting in hybrid networks (NSDHN). In one aspect, the disclosure teaches an efficient delivery decision mechanism that takes into account efficiencies that may be achieved by employing one network delivery system over another for any given area. In another aspect, the disclosure teaches how to dynamically select the bearer for IP multicast data delivery in hybrid networks. Also, the disclosure teaches a network delivery selector based on Simulated Annealing and genetic algorithms. The network delivery selector provides an extremely fast mechanism to establish an optimal delivery bearer dynamically. This allows the network delivery selector to combine unicast, multicast and broadcast network bearers in the same hybrid network to exploit their combined best properties and serve as many users as possible.
