    The proposal relates to simulating central pro- cessing units (CPUs). A CPU is a hardware arrange- ment with operand register (OR), flag' register (FR) and instruction decoder (ID). The CPU is usually coupled to a memory (M). A simulator is a computer (hardware) which represents the CPU (CPU': OR', IX', ID') and the...

    The following paper describes how configurable firmware for embedded controllers used in radio communication equipment can remove incompati- bilities between the fmware, the codeplug data lay- out and the RSS used for customer programming. In addition the amount of memory required for the firmware as well as for the...

    This paper deals with a method to insert chip components on printed circuit boards (pcb). The most known Insertion Automates are operating by setting the components serially in time. The printed circuit normally consists of simple passive chips like resistors and capacitors in his majority. Let us assume there arc 300...

    A called radio unit may transmit different types of acknowledgements to a calling radio unit, depending on whether a user answers a call, whether a call enters a stack or whether a voice message should be left. The acknowledgements can be used by a calling radio to provide call progress indica- tions, such as...

    The accuracy, repeatability and resolution of the received signal strength (RSSI) in a network sub- scriber unit are very dependent upon the characteris- tics of the individual hardware components. Due to variation in parts, the accuracy of RSSI measure- ments in a network subscriber unit has always been less than...

    On the current Iridium@ program, satellite to satellite communications is accomplished via four half duplex 12.5 MBPS burst rate K-Band RF crosslinks. Two of these crosslinks point fore and aft (In Plane Links) and two right and left (Cross Plane Links). Transmit and receive timing for all crosslinks are slaved...

    Legal evidence for the receipt of a mail message is difficult to obtain whenever the mail transfer sys- tem can not provide a digitally-signed receipt, usual- ly because of network constraints. For example, when two Local Area Network (LAN) enclaves are separated by a firewall (guard), local policy may disallow the...

    With the present emergence of far-reaching communication systems, the need for improved syn- thesizer performance has received renewed focus. Conjointly, synthesizers operating over several frequency decades and providing excellent phase noise, quick settling time, fine frequency step size and low spurious performance...

    For many products that involve secure commu- nications, there is the need for a highly non-deter- ministic random number generator. Most hardware random number generators (RNGs) can be catego- rized as either analog or digital devices. Most of the analog designs require a noise source, essentially a piece of circuitry...

    Many random access algorithms have been implemented, investigated and studied for a period of time in data communication industry. Basically these algorithms can be categorized into following three classes: 1. Generalized Aloha algorithm: Every network user monitors its status after transmitting its access request,...
