Latest Patents

One of Clarke's latest patents is related to radio positioning systems. This invention addresses the hearability problem in CDMA communications networks by utilizing a separate sampling device for each transmitter. The device sends a representation of the signals transmitted by that specific transmitter to a computing device. A cross-correlation process is performed between the representation sent back by the mobile terminal and the representation from the brightest transmitter. This method iteratively reduces the effect of the brightest signal on the remaining signals, allowing for more accurate extraction of useful signals.

Another significant patent is the radio location system measurement unit. This invention features a location measurement unit designed for a radio location measuring system. It includes multiple coupling devices that pick up signals from various base transceiver stations (BTSs) within a cellular radio communication system. A switching device connects these coupling devices, allowing for the selection of signals. The processed signals are then transferred to a calculation node for further analysis.
