Latest Patents

One of Pfeil's latest patents is titled "Method and apparatus for determining remote unit location using phased array antenna elements." This invention involves an apparatus and method that dynamically allocates radio frequency receive path resources as required by a programmable location engine. The programmable location engine employs cascaded time of arrival and direction of arrival algorithms to determine location data for each remote unit. The apparatus utilizes a phased array antenna and a programmable receiver switching apparatus, allowing multiple radio frequency receivers to receive different carriers on various phased array antenna elements. This innovative design enables the determination of both time of arrival and direction of arrival information.

Another significant patent by Pfeil is "Method and apparatus for estimating a channel parameter." This invention focuses on estimating mobile radio channel parameters by dynamically determining the delay offset, carrier frequency offset, and coherent averaging length that yield the optimum despreading gain for current channel conditions. By obtaining optimal despreading gain, the fidelity of desired channel parameter estimates, such as delay, phase, and complex impulse response, is significantly increased. This method expands the range of conditions under which these parameters can be feasibly measured.
