Latest Patents

William A Lindsay-Stewart holds a patent for a "Method and apparatus for measuring the impulse response of a radio." This invention involves a system designed to measure a multipath radio channel's impulse response by cross-correlating digital samples of a received pseudo-random signal with a digital copy of the transmitted signal. The system includes a transmitter that repeatedly sends the pseudo-random signal across a multipath radio channel. A receiver captures the transmitted signal along with its delayed versions, digitally sampling these signals. A computer then cross-correlates the samples with the stored digital version of the transmitted signal, producing a measure of the impulse response of the multipath radio channel.
