  • Patent number: 6735263
    Abstract: A method for coherent detection and demodulation of a FDMA signal, that is a superposition of amplitude modulated carriers, is provided. An array of special digital phase-locked loops (PLLs) is implemented in a digital signal processor (DSP) for processing the received signal after it is digitized, and for extracting the envelopes corresponding to each carrier. Each PLL is deliberately made to slowly respond to error signals in order to allow the loop to preserve its phase while the amplitude value of the envelope flips sign. A down-decimation technique is employed in order to reduce the computational load. This is achieved by applying a finite impulse-response filter (FIR) only once per each frame, thereby only a single multiplication of the frame by the vector of filter's taps is employed. A digital generation of sine and cosine sampled waveforms is employed inside a PLL by using a real-time solution of a difference equation.

  • Patent number: 6484131
    Abstract: This invention discloses a pose tracking apparatus operative to track the pose of a moving object based on magnetic flux measurements taken in the vicinity of the moving object. The pose tracking apparatus includes a non-linear Kalman filter-based tracker. The tracker is operated to receive magnetic flux measurements performed in the vicinity of the moving object, and to operate a non-linear Kalman-type filter on said measurements, thereby to generate information regarding the pose of the moving object. In addition, the pose tracking apparatus includes a pose indicator operative to provide an output indication of the information regarding the pose of the moving object.
