摘要： Techniques for reducing or eliminating effects of noise on a wireless communication system are provided. In one aspect of the invention, the technique comprises monitoring noise attributable to an interference source that may affect one or more components of the wireless communication system. The interference source being monitored is distant from the wireless communication system to the degree that noise arrives at the wireless communication system within a substantially point source-like angular range. For example, the noise may be attributable to the sun or tropospheric ducting. The technique then comprises initiating one or more operations, as a function of the monitored noise, to reduce or eliminate the effects of the noise attributable to the distant interference source at one or more of the components of the wireless communication system that are determined to be affected by such noise.

摘要： A thin film resonator (TFR) filter circuit including a plurality of TFRs connected in a series-shunt or shunt-series arrangement between input and output ports of the filter. A method is provided that allows for the shifting of resonant frequency sets in each TFR in respective series arms and shunt legs of the TFR filter circuit, as opposed to a conventional concatenating approach using a plurality of chained-up building blocks of TFRs, where resonant frequency sets in each of the series arms are equal, and where resonant frequency sets in each of the shunt legs are equal. Additionally, each TFR in the filter may have a unique parallel plate electrode capacitance, as opposed to the conventional concatenating approach where all series arm electrodes in the root filter design have equal capacitance, and where all shunt leg electrodes have equal capacitance. By shifting the resonant frequency sets and/or varying the electrode capacitance of the TFRs, a wider passband width may be achieved for a given return loss performance, as compared to conventionally designed filter circuits.

摘要： A method for controlling a wireless communications system is provided. A plurality of substantially identical base stations, each capable of being operated as both a primary agent and a secondary agent are deployed. The secondary agent is capable of communicating with a mobile device and the primary agent is capable of communicating with a network. A network active set associated with a mobile device is formed from a plurality of the base stations. One of the base stations in the network active set is selected to operate as the primary agent, and it communicates to the other base stations that the selected base station is operating as the primary agent. Thus, communications between the network and the mobile device are routed through the primary agent and the selected secondary agent.

摘要： The present invention provides a method for tuning a thin film resonator (TFR) filter comprising a plurality of TFR components formed on a substrate. Each of the TFR components has a set of resonant frequencies that depend on material parameters and construction. TFR bandpass filter response for example can be produced by shifting the set of resonant frequencies in at least one of the series branch TFR components so as to establish the desired shape of the bandpass response and the desired performance of the filter. The shifting may be advantageously performed by removing piezoelectric material from the series branch TFR component, providing a TFR filter with bandwidth and attenuation advantages over that conventionally achieved by down-shifting resonant frequency sets of the shunt TFR components by adding metal material. Additionally, the above method can be used to produce a stopband TFR filter with a desired response by removing piezoelectric material from the shunt branch TFR component, to up-shift the shunt TFR components' set of resonant frequencies with respect to the series branch TFR components.
