摘要： A femtocell increases efficiency and coverage of a macrocellular network operating in a co-channel manner within the macrocell spectrum by selecting subcarriers for its mobile station using both the subcarrier allocation map received from the macrocell and a spectrum sensing operation. Interference is avoided by selecting only subcarriers not allocated by the macrocell and subcarriers allocated to users not nearby to the femtocell. Interference is eliminated from the received signals using co-channel interference avoidance techniques. Selection of subcarriers for femtocell use may take into consideration inter-carrier interference detected.

摘要： The present invention provides a system and method for transmitting an ultrawideband (UWB) signal that is composed of an orthogonal frequency-division multiplexing (OFDM) based signal that is transmitted in an underlay manner and an impulse radio based signal that is transmitted in an overlay manner. The system and method are effective in determining an interference temperature for each of multiple carriers within the UWB signal and classifying each one of the multiple carriers of the channel as being an interfered carrier or a non-interfered carrier based on the interference temperature for each one of multiple carriers. The desired signal is then transmitted on the interfered carriers at a signal power that is not greater than the power limit of the underlay UWB policy and on the non-interfered carriers at a signal power that is greater than the power limit of the underlay UWB policy.

摘要： An apparatus, system, method and program detect and reduce interference in cell sites of a wireless communications network. A cell site from the cell sites of the wireless communications network is selected and signal code power measurements from mobile devices in the cell site are received so that the sources of signals being transmitted to the mobile devices can be determined. Interfering sources are determined based on the signal code power measurements and the active set of sources for the mobile devices. The signal code power measurements are summed and ranked, and interfering transmitters associated with the ranked signal code power measurements for the interfering sources are determined. The same procedure is repeated for all cell sites of the wireless communications network, and the transmitter that is an interfering source for the highest number of cell sites is selected as a problem (interfering) transmitter. The parameters of the problem transmitter and the corresponding antenna are altered and performance of the wireless network in a critical zone around the problem transmitter and interference in the cell sites interfered by the problem transmitter are monitored. Altering of the parameters of the problem transmitter and the corresponding antenna is performed continuously until a desired interference reduction is achieved in the cell sites interfered by the problem transmitter.

摘要： An apparatus, method and program reduce interference in interfered cell sites of a wireless communications network. A cell site is a region in which wireless communications are provided to mobile devices, and the interfered cell sites being cell sites where mobile devices are subject to interference signals from at least one interfering transmitter. A transmitter is selected from a list of interfering transmitters in need of adjustment and corresponding antennas. A critical zone is determined with respect to the selected transmitter. Parameters of the selected transmitter and the corresponding antenna are altered and performance of the wireless network in the critical zone around the problem transmitter and interference in the cell sites interfered by the problem transmitter are monitored. Altering of the parameters of the transmitter and the corresponding antenna is performed continuously until a desired interference reduction is achieved in the cell sites interfered by the selected transmitter.
