RSS signalOn the Relation Between Bandwidth and Robustness of Indoor UWB Communication
White Paper From these measurements, a single intuitive scalar is derived, which characterizes the small-scale fading encountered by a certain signal. This signal has been characterized by its lower frequency and bandwidth. [10 Jul 2008]
A High-Channel-Density, Ultra-High Bandwidth Reference Backplane Designed and Manufactured for 10 Gb/S NRZ Serial Signaling
White Paper Advancements both in active signal conditioning and passive interconnect technologies have made this happen. In the last 12 months 10Gb/s serial data transmission in copper backplane has moved from being a good possibility to a practical reality. [10 Jul 2008]
Robotics-Based Location Sensing Using Wireless Ethernet
White Paper This paper describes the design, implementation and analysis of a system for determining position inside a building from measured RF signal strengths of packets on an IEEE 802.11b wireless Ethernet net-work. [10 Jul 2008]
An Experimental Study of Localization Using Wireless Ethernet
White Paper Wi-Fi-based localization relies on the existence of one or more Wi-Fi devices in the environment to act as beacons, and uses signal strength information from those beacons to localize the robot. This paper studies the use of wireless Ethernet (Wi... [10 Jul 2008]
The Papoulis-Gerchberg Algorithm With Unknown Signal Bandwidth
White Paper The interpolation of low-pass signals with this algorithm can be done if the signal bandwidth is known. In practice, the signal bandwidth is unknown and has to be estimated by the user, preventing an automatic application of the Papoulis-Gerchberg... [08 Jul 2008]
Testing Challenges for 10 Gb/S Ethernet Over Twisted-Pair Cabling: New Installation and Testing Guidelines Help Combat Alien Crosstalk (AXTalk)
White Paper The physical link must be able to transmit the signal from the transmitter to the receiver over the desired distance and deliver the signal quality at its end, the input of the receiver. The receiver must also meet a set of performance parameters... [08 Jul 2008]
Increase Bandwidth in Medical & Industrial Applications With FPGA Co-Processors
White Paper Digital Signal Processing (DSP) in medical and industrial applications often has fundamental differences from the typical telecommunication application. Programmable Logic Devices (PLDs) have long been used as primary and co-processors in... [08 Jul 2008]
Implementation and Performance Study of a New NAT/Firewall Signaling Protocol
White Paper This new protocol allows end hosts to signal along a path to configure NATs and firewalls according to the data flow needs. The NAT/Firewall NSIS Signaling Layer Protocol (NAT/Firewall NSLP) is a path-coupled signaling protocol for explicit Network... [08 Jul 2008]
A Novel Coding Technique to Minimise the Transmission Bandwidth and Bit Error Rate in DPSK
White Paper The received signal is demodulated by using the present phase ö(t) and the two phases ö(t-Tb) and ö(t-2Tb). This paper proposes a novel coding technique that aims to reduce the Transmission Bandwidth (BT) and Bit Error Rate (BER) vis-a-vis... [08 Jul 2008]
On the Relation Between Bandwidth and Robustness of UWB Channel in Complex Confined Areas
White Paper The objective of this dissertation is to obtain a quantitative analysis of the relation between robusteness and signal bandwidth of the UWB channel propagation in underground mines. Ultra-Wideband (UWB) communication has been the subject of... [08 Jul 2008]
Active Ethernet I/O: A New Generation in IP-Based Data Acquisition and Control
White Paper However, this solution was not effective over long distances due to the inherent limitations of I/O signal transfer. Network hosts typically have to poll the I/O server repeatedly in order to obtain remote sensor data over an Ethernet network. [08 Jul 2008]
RF Over Ethernet for Wireless Infrastructure
White Paper The solution is general in nature, allowing for a variety of data content in many applications, including baseband interconnects, distributed antennas and signal processing clusters. Existing interconnects between RF and processing hardware have... [07 Jul 2008]
Lightpath-Level Protection Versus Connection-Level Protection for Carrier-Grade Ethernet in a Mixed-Line-Rate Telecom Network
White Paper The paper studies the problem of designing reliable and cost-efficient high-rate (100 Gbit/s) carrier-grade Ethernet in a multi-line-rate telecom network under signal transmission-range constraints. Ethernet is a success story in Local Area... [05 Jul 2008]
Ultra-Wideband: A Wireless Renaissance in the Making
White Paper Ultra-wideband is a wireless technology that transmits an extremely low power signal over a wide swath of radio spectrum, achieving data rates as high as 114 Mbps today. Unlike conventional radio systems that operate within a relatively narrow... [03 Jul 2008]
Synchronization in Interleaved OFDMA Systems
White Paper This paper investigates the base station receiver signal structure, and a structure based estimator is proposed for simultaneously estimating multiple users' carrier frequency offsets. Orthogonal Frequency Division Multiple Access (OFDMA) as a new... [03 Jul 2008]
