摘要： A communications stimulation system allows a user to perform a quantitative or subjective test of digital baseband devices over wireless channels using actual measured or modeled propagation data. The digital wireless communication simulation system is capable of simulating the transient nature of channels and radio hardware so that loss of synchronization can be included in the simulation. The simulator is a combination of computer software and hardware that computes a convolution, in the time domain, of a sequence of binary digits or data symbols (i.e., the data stream) with a computer model of a radio transmitter, a propagation channel or channels and a receiver. The transmitter typically comprises a coder, a pulse shaper, a modulator, and a spreader. The propagation channel or channels may include impulsive and average noise levels, co-channel interference and adjacent interference levels, fading and multipath propagation events, and non-linear channel and radio system effects. The receiver system typically comprises at least a filter bank, a demodulator, a despreader, a synchronizer, a detector, and a decoder. The data stream may either be random or applied by the user. The software computes the bit-by-bit sequence for replay at a later time. Once stored, the bit-by-bit error sequence can be clocked through a hardware data port and compared with an applied data stream in real time. The output of the hardware data port is a real time sequence of bits that has errors due to the bit-by-bit simulation computed earlier by the software.

摘要： A portable real-time monitoring system for field testing and troubleshooting a cellular telephone network, paging network, or mobile radio system employs a user friendly interface between a user and a scanning radio receiver which displays, monitors and stores parameters related to real-time performance. A portable all-band radio receiver capable of receiving cellular and paging frequencies is connected to a computer, such as, for example, a lap-top computer suitable for mobile operation at remote sites, personal computer (PC) or workstation. An interface circuit is installed within the radio receiver which taps available signals within the receiver as well as allows the computer to control the receiver frequency selection, band designation and demodulation setting. The interface hardware and microcode cooperate to process and decode received signals according to cellular and paging network industry standards. An application running on the computer is provided which utilizes the processed signals to permit complete automated reception, display and storage of cellular, paging, and mobile radio data as well as the signal strength (RSSI) for each signal. All monitored activity is displayed on the PC screen and is written to a disk in an organized ASCII or HEX file for instant retrieval and analysis. Masks can also be specified by the user which allow only selected data to pass or not pass through the system. The masks may be used to trigger alarms and print data when selected data is detected.

摘要： A coating process to infill high aspect-ratio vias and trenches in semiconductor substrates with dense boron for the production of neutron detectors and other devices uses a vacuum cathodic arc or other source of fully ionized boron plasma. Biasing of the substrate is used to impart energies to the plasma ions directing them toward the substrate, while repulsing the electrons. The full ionization produced by the source allows control of the energies of the boron ions by means of the bias voltage. The bias is alternated between coating deposition at low ion energies and sputtering of already coated material by energetic ions. Most of the sputtered material comes off the substrate top surface and between the trenches or vias and much of it is redeposited, thereby contributing to the infill. The process is suitable for carbon, boron or similar light elements, and is of particular interest for 10B, an element having exceptionally high thermal neutron cross-section.
