Abstract: An integrated circuit includes a reconfigurable FIR filter has an input port for receiving digital input signals and an output coupled to a coherent signal processor and a coherent memory. The FIR filter programmably provides filtered signals to the coherent signal processor for storage in the coherent memory. The integrated circuit further includes a sequential weight processor having an input coupled to an output of the coherent memory. The sequential weight processor includes a weight memory and operates to output symbol soft decision data resulting from processing the digital input signals. The integrated circuit is programmable into one of a plurality of operating modes, including at least one of a received signal acquisition mode, a channel estimator mode, an adaptive equalizer mode, and a channel-wise differential mode.

Abstract: An electromagnetic probe for the detection of both E-field and H-field radiation includes a quasi-isotropic E-field antenna and a quasi-isotropic H-field antenna. The quasi-isotropic E-field antenna includes three mutually orthogonal surface area antenna elements which define three mutually perpendicular planes and an apex. Each surface area element is responsive to E-field radiation normal to the surface of that element and produces an output voltage signal proportional thereto. The quasi-isotropic H-field antenna includes three mutually orthogonal electrically small loop antenna elements. Each loop antenna element is responsive to H-field radiation which is incident normal to the plane of the element. Each loop antenna element produces an output voltage signal proportional to the field strength of the H-field radiation. The H-field antenna is affixed substantially proximate to the apex which is defined by the E-field antenna.
