Title: Etty Lee: Innovator in Spectrum Sensing Technology
Introduction
Etty Lee is a prominent inventor based in Winchester, MA (US), known for her contributions to the field of spectrum sensing technology. With a total of two patents to her name, she has made significant strides in improving the detection of radar signals in shared spectrums.
Latest Patents
Etty Lee's latest patent is titled "Method, system, and apparatus for spectrum sensing of radar signals." This innovative technique enhances the ability to detect the presence or absence of predetermined signals within a shared spectrum. The process involves down-converting received RF signals to baseband signals, which are then analyzed by a spectrum sensor. The sensor transforms the baseband signal into the frequency domain using a fast Fourier transform, generating a set of frequency components. These components are multiplied with the frequency response of a matched filter, which has coefficients corresponding to the predetermined signal. The matched-filter output is converted back to the time domain, allowing the sensor to determine signal power and compare it with a known threshold. This determination can lead to the reconfiguration of transmitters operating in the same spectrum, thereby optimizing signal detection and transmission.
