摘要： a Method and Apparatus for Automatic Jammer Frequency Control of Surgical Reactive Jammers is disclosed. The system and method to autonomously and selectively jams frequency-hopping signals in near real-time. The system has the ability to automatically detect short duration signals (such as those output from frequency hoppers), to automatically determine if detected signal(s) should be jammed, and subsequently to automatically and extremely quickly activate the jamming transmitter on the frequency-hopper transmitter's frequency. Furthermore, the system improves upon the FFT-based front-end system by incorporating a module that automatically and iteratively comparing the digital FFT results to the analog RF signal to arrive at a total frequency offset between the FFT results and the analog signal so that the transmitted jamming signal will be more accurately applied on the desired or target frequency. Finally, the system provides a programmable user interface so that operators can set up the system to act autonomously as intended, such that operator intervention is unnecessary when the system is placed in jamming operation mode.

摘要： The present invention is related to a method and apparatus for automatic frequency correction of a local oscillator. The apparatus receives a carrier signal. The carrier signal includes a code sequence known to the apparatus. The apparatus downconverts the carrier signal to a baseband signal using the local oscillator. The apparatus performs a block correlation of the samples of the baseband signal with the known code sequence to generate a frequency error signal. The frequency error signal is fed back to the local oscillator to correct the frequency error.

摘要： An apparatus for frequency synchronization is proposed to detect a synchronization signal from the baseband signals. It is featured that three types of detection values are introduced to detect whether the synchronization signal is received or not. More particularly, the claimed frequency synchronization apparatus provides at least one signal power generator for receiving a predetermined number of symbols of the baseband signals, and further calculating an average quality value therefore. Further, the apparatus includes a signal selector for producing a first detection value according to the average quality value. Still further, the apparatus provides a decision unit to produce a second detection value. After that, a signal processor inside the decision unit is used to calculate a third detection value as combining the first detection value and the second detection. Consequently, the decision unit particularly decides whether the synchronization signal is received or not in reference with the third detection value.

摘要： A receiver is tuned to a transmission frequency of a data signal after the receiver has already locked onto a frequency carrying the data signal. A frequency offset between a locked frequency of a tuner on the receiver and the actual transmission frequency is determined by a comparator. If the frequency offset is greater than a threshold value, then the tuner is stepped to another frequency and the frequency offset is determined again. The direction of the tuning step can be determined by comparing multiple frequency offsets. An average value of multiple frequency offset measurements may also be used to determine if the tuner should retune to another frequency by comparison with the threshold value.

摘要： A control unit supplies a new control value to a frequency source. The value is determined by the frequency source frequency and the reference frequency. The control unit further calculates a rate of change value based at least on the new and a previous control value if there is communication with the reference frequency generator and stores these values in corresponding stores. Another control unit calculates a new control value based on the rate of change value from the rate of change store and the last used control value from the control value store and supplies the new control value to the frequency source if there is no communication with the reference generator.
