Latest Patents
One of her latest patents is titled "Optimal initial gain selection for wireless receiver." This invention involves an OFDM wireless transceiver that utilizes a digital automatic gain control (AGC) module. The digital AGC module is designed to set an initial gain value for mapping a received wireless signal to a specific power value for an input circuit with a defined input range. The initial gain value is determined based on the prescribed input range and a specified signal-to-noise ratio. If the first power value of the received signal does not meet the input range, the AGC module calculates an optimum gain relative to the initial gain value. Conversely, if the first power value exceeds the input range, the AGC module sets the gain to a minimum value.
Another notable patent is "Autocorrelation threshold generation based on median filtering for symbol boundary detection in an OFDM receiver." This invention features an autocorrelation circuit that generates autocorrelated power values from samples of received short preamble symbols in a data packet. A median filter is employed to produce a median autocorrelation value from a minimum number of autocorrelated signal values. A comparator detects the symbol boundary by identifying the end of the short preamble symbols based on the autocorrelated signal values falling below a threshold derived from the median autocorrelation value. This dynamic calculation of the threshold minimizes errors caused by varying energy levels or propagation characteristics, while the median value reduces noise effects and false detection errors.
