Presence-aware cellular communication system and method
InactiveUS20100056184A1Increase capacityReduce consumptionPower managementAssess restrictionAir interfaceCellular communication systems
A cellular communication system comprises a network supporting user equipment over an air interface, the network having a hierarchical cell arrangement with overlay cells and underlay cells. An underlay base station is associated with a subset of registered user equipment. An activation server switches the underlay base station between an inactive mode and an active mode in response to detecting that registered user equipment meets a location criterion. The underlay base station only supports user equipment when in the active mode, e.g., it may only transmit a pilot signal in this mode. Interference and power consumption may be substantially reduced by sending the base station into the inactive mode thereby resulting in increased capacity of the cellular communication system as a whole.

Method and system to avoid inter-system interference for phase-based time-of-flight systems
ActiveUS7405812B1Likelihood of interferenceReduce distractionsOptical rangefindersElectromagnetic wave reradiationClock rateOptical energy
Inter-system interference cross-produce P12 is reduced in a phase-based TOF system by randomizing instantaneous phase and / or frequency within a capture interval (or detection integration period). In one aspect, the TOF clock system frequency preserves long-term clock frequency stability but intentionally includes random or pseudo-random clock noise. The noise ensures the generated clock signals are temporally imperfect and lack substantial perfect periodicity. A second aspect causes the TOF clock system to hop frequency, preferably pseudo-randomly. TOF system homodyning favors detection of optical energy whose frequency correlates to the time-varying frequency of the emitted optical energy. Thus, the varying spectral spacing of the emitted optical energy reduces likelihood that an adjacent TOF system at any given time will emit optical energy of an interfering frequency. At least one aspect is employed, both aspects being mutually complementary to reduce the cross-correlation product P12 without substantially affecting TOF system performance.

Method and system for reducing potential interference in an impulse radio
InactiveUS6914949B2Reduce distractionsReduce broadband noiseError preventionTransmission systemsInterference ratioRadio reception
Potential interference is reduced in an impulse radio. A signal including an impulse signal and potential interference is received by the impulse radio. The impulse signal includes a sequence of impulses. The sequence of impulses of the received signal is sampled at a sequence of data sample times to produce a sequence of data samples. The received signal is also sampled at a plurality of time offsets from each of the data sample times to produce a plurality of nulling samples corresponding to each of the data samples. A separate sequence of nulling samples for each of the time offsets is thereby produced. Each of the data samples is then separately combined with a corresponding nulling sample from each of the separate sequences of nulling samples to produce a separate sequence of adjusted samples corresponding to each of the time offsets. A separate quality metric, representative of a signal-to-interference level, is then determined for each of the separate sequences of adjusted samples. A preferred sequence of samples is selected for further signal processing based on the determined quality metrics. Alternatively or additionally, one of the plurality of time offsets is selected as the preferred time offset based on the determined quality metrics.

In wireless system, a group of Basestations (BTSs) can be managed by a centralized network management identity or can be self-organized by communicating with each other via wireless air-interfaces or wired interfaces. One such example are Femtocell systems. When the BTSs are using the same frequency for transmitting and receiving with relatively large transmitting power and when they are closer to each other, performance of such a system and user throughput or QoS (Quality of Service) gets degraded due to the interference between the BTSs and among the users. Smart antenna technique can be used in a coordinated way among a group of BTSs, such as Femtocells, to avoid or reduce interference or manage how interference happens to achieve performance enhancement such as higher system throughput or better QoS to individual applications.
