20080238777 | SYSTEM AND METHOD FOR ENHANCIN THE ACCURACY OF A LOCATION ESTIMATE - A method for enabling a system to enhance the accuracy of a location estimate modifies weights in a weight matrix associated with receiver station measurements in parallel with successive refinements of the location estimate. In a typical location estimation scenario, several receiving stations simultaneously derive measurements of a signal from the emitter. Any one of these measurements is in general some function of the emitter location and the receiving station location. The aggregate of these measurements is often in excess of the minimum number of measurements required to provide an estimate of the emitter location. Where such an excess exists, the method proceeds by modifying the weights associated with the measurements in parallel with successive refinements of the location estimate. The method can be implemented over various cellular protocols with a consistent and significant enhancement in the accuracy of location estimates. | 10-02-2008 |
20080248745 | System and Method for Identifying the Path or Devices on the Path of a Communication Signal Using (1+r(T)) Amplitude Modulation - A system and method of applying a known modification to a signal to enable a determination of a signal received by a first node is received directly from a second node or indirectly through a repeater. The repeater receives a primary signal and creates a secondary signal as a function of the primary signal and a known modification, wherein the known modification identifies the repeater. The primary signal is transmitted and injected with the secondary signal as the first signal to the primary receiver. | 10-09-2008 |
20090215389 | System and method for identifying the path or devices on the path of a communication signal - A system and method of applying a known modification in the form of a distortion to a signal to enable a determination if a signal received by a first node is received directly from a second node or indirectly through a repeater. The repeater receives a primary signal and creates a secondary signal as a function of the primary signal and a known distortion, wherein the known distortion identifies the repeater. The primary signal is transmitted and injected with the secondary signal as the first signal to the primary receiver. | 08-27-2009 |
