    Abstract: A method for differential phase evaluation of M-ary communication data is employed in which the data consists of N sequential symbols r1 . . . rN, each having one of M transmitted phases. Selected sequences of N−1 elements that represent possible sequences of phase differentials are evaluated using multiple-symbol differential detection. Using r1 as the reference for each phase differential estimate, sN−1 phase differential sequences are selected in the form (P2i, P3i, . . . , PNi) for i=1 to s for evaluating said symbol set, where s is predetermined and 1

    Abstract: A multi-stage receiver and method for recovering a traffic signal embedded in at least one received signal. The multi-stage receiver includes a plurality of sequential detection stages for processing each received signal and providing successively better estimates of the traffic signal. The multi-stage receiver includes, for each received signal, a first processing stage and a second processing stage. The multi-stage receiver also includes a final processing stage connected to the second processing stages. Each first processing stage generates a first estimate of the traffic signal from the respective received signal and each second processing stage generates a set of energy values from the respective first estimate of the traffic signal and from the respective received signal. The final processing stage combines the set of energy values from each second processing stage and generates an improved estimate of the traffic signal. By employing multiple stages in the receiver, there is an improvement in successive estimates of the traffic signal.

    Abstract: A circuit for filtering single event effect (SEE) induced glitches is disclosed. The circuit for filtering SEE induced glitches comprises an SEE immune latch circuit and a delay element. The SEE immune latch circuit includes a first input, a second input, and an output. The SEE immune latch changes from one state to another state only upon having incoming input signals of identical polarity being applied contemporaneously at both the first input and the second input. The first input of the SEE immune latch circuit is directly connected to a signal input, and the second input of the SEE immune latch circuit is connected to the signal input via the delay element. The delay element provides a signal delay time equal to or greater than a pulse width of an SEE induced glitch but less than a pre-determined pulse width of an incoming signal at the signal input under normal operation. By connecting the delay element between the signal input and the second input of the SEE immune latch circuit, a temporal separation greater that the duration of an SEE induced glitch can be achieved on the data being drive into the first and the second inputs of the SEE immune latch circuit. As a result, SEE induced glitches will not be written into the SEE immune latch circuit.

    Abstract: A method for synthesizing nature-identical raspberry ketone is provided, belonging to the technical field of pharmaceutical synthesis. The nature-identical raspberry ketone is obtained by using natural p-anisaldehyde and natural acetone as initial raw materials to allow three-step continuous reactions of basic resin-catalyzed Claisen-Schmidt condensation, enzyme-catalyzed reduction, and demethylation of sodium ethanethiolate. The synthesis method is safe and clean, and has a stable yield reaching approximately 85%, providing a basis for industrial continuous production. The synthesis method not only meets the requirements for clean production, but also saves labor costs by virtue of the continuous process, and is suitable for large-scale industrial production.
