Latest Patents

One of his notable patents is titled "Constant ratio coding for multipath rejection and ECCM enhancement." This patent discloses a method for encoding signals for transmission that provides signals with specifiable autocorrelation properties and low predictability. The coding method is designed to enhance the accuracy of time of arrival measurements in the presence of noise or multipath interference, particularly from skywaves in systems such as LORAN. The method achieves low autocorrelation function values at time offsets that correspond to the expected delay between direct waves and skywaves. This is accomplished by constructing the codeword from an Nth difference constant ratio codeword, where the expected time delay is equal to N-bits. The pseudo-random generation of both constant ratio codewords and transmitted codewords results in a signal that is very difficult for unintended recipients to predict, thereby reducing the effectiveness of jamming or electronic countermeasures.
