Latest Patents
Wissel's latest patents include a method of and apparatus for transmitting and recovering offset QPSK. This innovation involves deriving bit timing references at a receiver for a carrier modulated by OQPSK. The carrier is transmitted with a constant reference phase modulation during a first interval, followed by rotational phase modulation representing binary bit values in a subsequent interval. This method allows for effective synchronization at the receiver, ensuring that the frequency and phase lock are maintained during the reception of the rotational phase modulation.
Another significant patent is the synchronized receiver power system. This invention describes a portable radio receiver powered by a battery, which includes various amplifiers and a frequency synthesizer. The system is designed to minimize the injection of spurious signals by using a synchronizing source that is FM modulated by an audio source, spreading harmonics over a predetermined spectrum.
