Abstract: Signal detection assisted by use of moving antennae. A signal of interest may be detected in signal samples measured by a single antenna installed on a moving platform. A first sample is collected at time T1 and a second signal sample at time T2 by the single antenna. The first signal sample is treated as having been received by a first antenna mounted on the moving platform and the second signal sample is treated as having been received by a second antenna mounted on the moving platform. The samples are processed by a receiver of the first and second signal samples to detect the signal of interest.

Abstract: Self-configurable wireless network with cooperative interference measurements by base stations. A mini-cell system comprises a plurality of mini-cells. Each mini-cell comprises a communications system for establishing communications with and among remote devices and a signal collection system that provides connectivity to a signal collection network. The signal collection system comprises a scanner and a signal analyzer. The communications system and the signal collection system communicate with a local network controller via the signal collection network to report information about the mini-cell and signals that are received at the mini-cell location. The local network controller may process information received from the mini-cell about its configuration and its own signal and information received from the signal collection system to determine whether to reconfigure the network to mitigate interference and to optimize the mini-cell system.

Abstract: A method and apparatus for identifying signal sources in a multi-source signal. Levels of signal components transmitted by each of the co-channel base stations in the area under test in a wireless network are measured and associated with the appropriate (originating) base station in the presence of co-channel and adjacent-channel interference without interrupting service by sensing and responding to received, variable, patterns.

Abstract: The invention provides a method and a device for communicating a signal over a power line. One embodiment may comprise a length of power cable that comprises a center conductor substantially surrounded by an insulator. A concentric conductor is disposed external to the insulator over a first portion of the cable. A coupling conductor may be disposed concentrically around a second portion of the cable external to said insulator and having a first end and a second end. The concentric conductor is absent in a manner to form a gap between the concentric conductor and the first end of said coupling conductor. A transceiver cable is coupled to the first end of said coupling conductor and a common mode choke may be disposed substantially around the entire circumference of a portion of said coupling conductor. Finally, the second end of the coupling conductor may be coupled to ground through a convenient neutral conductor.

Abstract: A method (and system) for quantifying a three-dimensional model of interference in a cellular wireless communication network. The model is derived from the acquisition and analysis of composite signals as part of a survey of ground-level locations and above-ground-level locations within the intended coverage zone of the cellular wireless communication network. Reliable identification and correlation of signal components are derived by analysis of the acquired composite signals that uses time-of-arrival of a known part of a signal (e.g., the FCCH burst used in GSM for frequency correction).
