Abstract: A method and apparatus for generating reference signatures for use in geolocation in a cellular wireless communication system is provided. A first signature for a mobile communication unit comprises location information, a timestamp, and radio frequency measurement information obtained by a mobile communication unit at a location, but does not contain identification information for the mobile communication unit. The first signature is compared to signatures in a database, to identify a second signature that has a timestamp and radio frequency measurement information that correspond to those of the first signature. A reference signature is created by combining at least a part of the first signature with at least a part of the second signature. Repetition of the comparison and combination steps creates a database of reference signatures, for use in geolocating other received call signatures.

Abstract: A method and system for verifying a location value reported by an electronic device. The reported location value and spectrum sensing data containing signal strength measurements for each channel of plural channels are received from the electronic device. A predicted RF footprint for the reported location is generated. The predicted RF footprint includes signal strength values for each of the plural channels. Each signal strength value is representative of RF energy that the electronic device ought to detect if the electronic device is actually present in the reported location and each signal strength value is determined as a function of known characteristics of radio devices with known locations. A determination is made as to whether the received signal strength measurements and the predicted RF footprint sufficiently correlate to validate that the electronic device made the signal strength measurements at the reported location.

Abstract: The disclosure relates to a transmission scheme for nodes in a network. More specifically, the disclosure relates to an acknowledgment scheme that minimizes energy requirements for an acknowledgment of a transmission between nodes. The disclosure describes that an energy constrained node may transmit to other nodes in a network and may only require that an acknowledgment of that transmission is received from at least one of the proximal recipients, which may or may not be the ultimate target. In order to minimize the complexity of the receiver in a node and its energy requirements, the acknowledgment scheme may employ simple on-off keying (OOK) irrespective of the modulation technique of the sending transmission. The acknowledgment comprises a series of OOK pulses sent at a specified time after receipt of the transmission. In addition, simultaneously received acknowledgments can be processed and verified without confusion.

Abstract: Until when a desired signal is received in a reception mode, a level comparator extracts a portion of a frequency-domain signal output from a Fourier transformer, the portion matching with the frequency of the desired signal, and, when the reception level of the extracted portion matching with the frequency of the desired signal is higher than a predetermined threshold value, determines that an interference signal exists. An LO frequency controller sets the frequency of a local signal (LO) based on the determination result in the level comparator such that the frequency of intermodulation distortion caused by the interference signal becomes an intermediate frequency of the frequency band of the desired signal. When it is determined that the interference signal exists, an RX controller changes gain settings of a low-noise amplifier circuit and gain settings of a variable gain amplifier circuit and changes the cutoff frequency of a filter circuit.
