Cisco, Philips, and Emergin Collaborate on Patient Monitoring Solution That Delivers Immediate Waveform and Text Medical Alarms to Clinicians
White Paper Healthcare organizations aren't challenged with workflow automation - they expect partners to integrate their systems in a manner that improves a caregiver's effectiveness and efficiency. Clinicians can now receive mobile medical alarms,... [07 Jun 2006]
Peter Cochrane's Blog: Lab on a laptop
Comment From the time waveform I could see evidence of at least two harmonics and, with a lot of expansion, the presence of 50Hz power hum from the pick up feed/amplifier. Written at the Dayton, Ohio airport and dispatched to... [08 Dec 2005]
Experiences Implementing GSM in RDL (the Vanu Radio Description Language)
One important goal for software radio languages is portability, which is the capability to execute a waveform application on hardware platforms from different manufacturers. This paper describes RDL and reports the... [16 Nov 2005]
Digital Signal Processing and Filtering: GSM Codec
The conversion of analogue speech waveform into digital form is usually called speech coding. A major benefit of using speech coding is the possibility to compress the signal, that is, to reduce the bit rate of the... [16 Nov 2005]
A Prototype All-Software Public Safety Interoperability System
A prototype waveform interoperability system has been built by Vanu, Inc.for the US Army U.S. Army Communications-Electronics Command (CECOM). The system enables law enforcement and public safety agencies with... [16 Nov 2005]
Real Time Data Transmission Over GSM Voice Channel for Secure Voice & Data Applications
The modulated waveform is then transmitted over the GSM voice channel, which can be demodulated and decrypted at the receiver. This paper describes a real time prototype implementation of a system, which enables secure... [15 Nov 2005]
The Structure and Generation of Robust Waveforms for AM in Band on Channel Digital Broadcasting
White Paper This paper focuses on the generation and transmission of the AM IBOC waveform, including a description of the characteristics and features of the system. A robust In-Band On-Channel (IBOC) Digital Broadcasting system for... [26 Jul 2005]
Analysis of PHY Waveform Peak to Mean Ratio and Impact on RF Amplification
In forming the IEEE 802.16.3 standard, TG3 must evaluate the system level impact of PHY layer modulation on the RF subsystems at basestation and, to a greater extent, at the subscriber. The RF transmitter dominants power consumption and... [30 Mar 2005]
OFDM for Spectrally Efficient Communications in a Dynamic Multipath Environment
White Paper This paper defines the HDR LOS waveform and characterizes the associated link performance. Packet communications over a terrestrial line-of-sight channel using a mobile wireless network is an extreme challenge due to the... [02 Nov 2004]
CDMA Capacity
White Paper In such settings, each user modulates a preassigned (pseudo-) random signature waveform and transmits information independently of, and possibly concurrently with, other users. Code-division multiple access schemes allow... [24 Jul 2004]
