Latest Patents

Hsu's latest patents include a "Code division multiple access receiver and method for processing signals thereof." This invention provides a Code Division Multiple Access (CDMA) receiver that samples a received CDMA signal into multiple samples. The receiver consists of a sampling control module, a code generator, and several despreaders. The sampling control module delays the samples for various lengths to obtain delayed samples corresponding to each delay length. It also adjusts the timing of the sampling trigger signal and the code generation trigger signal based on a sampling timing adjustment signal. The code generator produces a despreading code according to the code generation trigger signal, while each despreader decimates the delayed samples to obtain output signals.

Another significant patent is the "Apparatus and method for reducing complexity of matched filter." This invention involves an apparatus for determining multipath correlations among a search range of input data. The multipath searcher includes a pseudo noise (PN) code generator, a correlator, and a data combiner. The PN code generator creates a first PN code for the first multipath component of the input data and generates a second PN code for the second multipath component after a specified period. The correlator then correlates the input data with both PN codes to produce correlations, which the data combiner uses to identify the primary multipath component with the highest correlation.
