Latest Patents
Bradley's latest patents include a method and apparatus for generating timing phase error signals in PSK. This invention involves a circuit arrangement that combines measures of single phase error for a received data signal in a PSK demodulator. It produces a timing phase error signal that controls the phase of a local clock timing signal in the demodulator. The demodulator generates a digital word that defines differences between the phases of decoded phasors at adjacent sample times. Additionally, he has developed an 8-phase PSK modulator, which comprises logic circuitry for converting tribits of input data into binary control signals. This modulator utilizes a pair of 4-phase signal generators to produce resultant vector signals that generate the phasors of an 8-phase signal set.
