Abstract: A device and method for receiving and reconstructing signals with improved perceived signal quality in a digital communications system is disclosed. The device and method utilize side information defining the quality or accuracy of recovered digital symbols representing an information signal and also utilizing past frame erasure information to determine whether to erase or use a frame to reconstruct the original information signal even though an error detection mechanism indicates that no error exists in the recovered digital symbols of the frame.

Abstract: The present invention provides a battery-powered radio transceiver for transmitting and receiving digital signals and method of operation for reducing electrical power consumption and thereby improving battery life between recharges. The radio transceiver includes an operator interface and a transmitter, electrically connected to a microphone in the operator interface, to convert speech signals into digital radio frequency (RF) signals for transmission. A receiver is electrically connected to a speaker in the operator interface to receive digital RF signals and to convert the RF signals into audio signals from the speaker. A microprocessor electrically connected to the operator interface, the transmitter and the receiver controls the operation of these components in processing telephone calls. An electrical storage battery is electrically connected to the microprocessor to supply electrical power to the microprocessor, the operator interface, the transmitter and the receiver via the microprocessor.

Abstract: A method of mass producing printed circuit antennas is disclosed including the steps of providing a substrate of dielectric material having a first side and a second side, removing portions of the substrate to produce an array of interconnected segments of desired size, fabricating a main radiating element on the first side of each substrate segment, overmolding each substrate segment with a protective dielectric material, and separating each substrate segment from the dielectric substrate to form a plurality of individual printed circuit antennas. Preferably, each of the foregoing steps are able to be performed on each substrate segment substantially simultaneously. The method may also include the steps of freeing one end of the substrate segments, attaching an electrical connector to each substrate segment, and overmolding the electrical connector for each of the substrate segments prior to the separating step.

Abstract: A RF site link for communicating between a centralized switching system and a plurality of mobile communications RF base stations is disclosed. The RF site link includes a plurality of RF link devices connected to centralized switching equipment. The RF link devices transmit signals to and receive signals from the remote base stations over the same working channels that the base stations use to communicate with the mobile or portable radios within each of the base stations' areas of operation. A RF control link is provided to control the assignment of the working channels between the centralized switching equipment and each of the base stations within the system.

Abstract: Hot electron injection into the gate oxides of MOSFET devices imposes limitations on the miniaturization of such devices in VLSI circuits. A buried channel with a graded, buried spacer is provided to guard against hot electron trapping effects while preserving process and structure compatibility with micron or submicron VLSI devices. The channel current is redirected into a buried channel at a distance away from the interface in the vicinity of the drain region where the hot electron effect is most likely to occur.
