Abstract: The invention is an apparatus and technique for tuning the cross coupling of resonators (302a, 302b...302e) in a dielectric resonator circuit. A cross coupling element (312) such as a coaxial cable having a first end (312a) positioned adjacent a first resonator (302b) in the circuit and a second end (312b) positioned adjacent a second resonator (302e) is supported on the housing (301) of the circuit intermediate its first and second ends. At least one end of the cross coupling element is in contact with a cross coupling tuning element that extends through an external wall of the housing so that it can be manipulated from outside of the housing (301) to move the corresponding end of the cross coupling element (312) relative to the adjacent resonator inside the housing (301) without opening the housing.

Abstract: The invention is a method and apparatus for dissipating heat in a dielectric resonator circuit in which resonators are mounted to an enclosure by highly thermally and electrically conductive supports, such as metal rods, that pass through the longitudinal through hole in the center of the resonator. The supports preferably are attached within the through holes by a highly thermally conductive, but dielectric sleeve positioned between the support and the resonator. The rod or support has a diameter selected to minimize any reduction in quality factor, Q, for the circuit. Alternately, the support can be a highly thermally conductive dielectric and the inner wall of the through hole can be metalized.

Abstract: A method and system is provided for improving bit error rate (BER) performance in delay spread fading conditions, such as the fading associated with simulcast systems. BER is improved through novel symbol synchronization that comprises oversampling an input signal (602A, 602B) and filtering the samples to determine a composite symbol sample point that converges toward the center (510, 514, 516) of the signal's effective eye pattern. The composite symbol sample point may be an average of previous composite symbol sample points and an instantaneous sample point (614) determined based on samples from a synchronization field (748, 796) of the signal. The updated composite symbol sample point may be utilized for future sampling of the incoming signal.

Abstract: A radar system (25) and method for determining the range and, optionally, the azimuth of a target, while maintaining a high transmitting duty factor is provided. A waveform generator (30) is connected to an antenna aperture by a transmit-receive switch (32,34), and the waveform is transmitted for more than half of the period of time of the sum of the transmission period and the receiving period. For a frequency-modulated continuous-wave waveform (FMCW), the receiver may be turned on for short intervals at a rate which is at least the Nyquist rate for the signal received from at target. A monopulse or frequency-scanned antenna may be used to determine azimuth as well as range.

Abstract: A distributed Internet Protocol (IP) voting system and method for use in Land Mobile Radio (LMR) Systems having a central send-and-receive site (12) and one or more receive-only sites (26). In the distributed voting system, receive-only sites (26) are directly linked to a control point (41) using a network (40) and associated packet transmission protocol. This may be a high-speed asynchronous data link such as a standard IP network link. Each remote site (26) receiving digital data, calculates a bit error for that data. This error calculation is incorporated into the data header information. The data header information and data are placed in an IP packet and transmitted as a User Data Protocol (UDP) message to the control point. The control point (41) selects the lowest bit rate data message, or the first control message, and retransmits it using a standard radio air interface protocol, such as the APCO Project 25 air interface protocol.
