Latest Patents

Fraser's latest patents focus on a spread spectrum apparatus designed for use in communication systems. One embodiment of his invention features a spread spectrum transmitter that utilizes a voltage-controlled oscillator (VCO) to generate a carrier signal. The frequency of the oscillator is controlled by the output of a correlation code generator and a data generator, which are coupled to a varactor in the oscillator. This design eliminates the need for sidelobes associated with mixers, enhancing the overall performance of the system.

In another embodiment, Fraser simplifies the tuning of the transmitter by separating the outputs of the correlation code generator and data generator from the output of a phase detector. Additionally, he employs a high-gain differential amplifier to couple these outputs to the varactor, further eliminating the need for manual tuning. His innovative approach includes modulating the VCO with a special code as it comes up to speed, which reduces interference with other narrowband receivers. The spread spectrum receiver he developed features separate narrowband channels for locking onto signals and recovering data, providing high interference immunity and facilitating faster data recovery.
