Lower bounds on the information rate of intersymbol interference channels based on the Ungerboeck observation model

We consider the problem of lower bounding the information rate of intersymbol interference channels via Monte Carlo algorithms. We adopt a novel approach based on the Ungerboeck observation model, unlike the existing ones that are all based on the Forney model. The two approaches, yet equivalent in the case of full-complexity detection, lead to different results in the case of reduced-complexity d

Personligt lärande i grupp på nätet

UCLUs lunchseminarium den 8 oktober. Håkan Eftring, avdelningsföreståndare och studierektor på Certec, avd. för rehabiliteringsteknik, berättade om sina erfarenheter av institutionens storsatsning på nätburen distansutbildning alltsedan 1996.

IC-Project and Verification Course: Teaching Top Down Analog/Mixed Signal Design

This paper describes a project course that focuses on the design of analog and mixed signal circuits through a systematic top down design flow. In the project, the student will be involved in the planning, modeling, circuit level design, physical level implementation and measurement verification of for example a successive approximation (SA) ADC or a class-D audio amplifier. Throughout the project

An Approach for Designing Management Support Systems: The Design Science Research Process and its Outcomes

Design science research involves creating and evaluating innovative methods and approaches to be used in design practice. We present an approach to be used in the process of designing Management Support Systems (MSS). The nature of managerial work makes the design, development, and implementation of MSS a major challenge. The MSS literature suggests that determining MSS requirements and specificat

Neuropathy in female dental personnel exposed to high frequency vibrations

Objective-To evaluate early neuropathy in dental personnel exposed to high frequency vibrations. Methods-30 dentists and 30 dental hygienists who used low and high speed hand pieces and ultrasonic scalers were studied, and 30 dental assistants and 30 medical nurses not exposed to vibration (all women). Vibrotactile sensibility, strength, motor performance, sensorineural symptoms and signs, and vas
