Latest Patents
One of his latest patents is titled "Multipath channel tap delay estimation in a CDMA spread spectrum receiver." This invention presents a method and apparatus for estimating channel tap delays of multipath components in a CDMA received signal. The search for the tap delays is divided into two phases: a coarse resolution quick search and a finer resolution slower search. The initial phase generates a rough estimate of the location of the tap delays, while the subsequent phase resolves any ambiguities present in the initial estimates.
Another significant patent is the "Whitening matched filter for use in a communications receiver." This novel filter is constructed by cascading a matched filter and a noise-whitening filter. The matched filter's response is derived from the time-reversed complex conjugate of the channel impulse response. The whitening filter is designed to process data received before and after the training sequence, enhancing the overall performance of the communications receiver.
