Latest Patents
One of Averst's latest patents is titled "Method and apparatus for Fast Fourier Transform based maximal ratio." This invention describes a method and apparatus for diversity-combining radio signals received from multiple branches. Each radio signal consists of several subchannels, which are digitized into digital samples and converted into frequency domain signals. A weighting factor is determined for each branch and subchannel based on instantaneous signal energy and noise power. The resulting weighted frequency domain signals are combined to produce a diversity-combined frequency domain signal for each subchannel.
Another significant patent by Averst is "Method and apparatus for carrier tracking and demodulation." This invention involves a frequency shift keyed receiver that estimates a carrier frequency and demodulates symbol values associated with that frequency. The receiver digitizes the radio signal during symbol intervals and converts it into a frequency domain signal. A windowing function is applied to locate a frequency distribution that corresponds to predetermined frequency offsets, allowing for accurate carrier frequency estimation and symbol demodulation.
