Open Systems Interconnection (OSI) is intended to facilitate interworking between data terminal equipments (DTEs) of different designs and from multiple vendors, thus providing the user community with a broad level of independence in the procurement of IT equipment. Whilst OSI local area network (LAN) standards have aimed to fulfil this objective, actual variations in data rates, media types and c... View full abstract»

The design of a fuzzy controller is discussed which uses roll and roll rate as input and fin demand as output to stabilise the roll motions of a modern warship. Owing to the nonlinear characteristics of the warship roll dynamics, it was found to be necessary for the fuzzy controller to have multiple output fuzzy-set options which are invoked at different ship speeds and rudder demands. Simulation ... View full abstract»

In high-density recording, the performance of the conventional Viterbi decoder for FM recording code is degraded by the influence of the correlation between samples of the noise at the discrimination point. A decoding method is therefore proposed which uses a Viterbi decoder whose form assumes a simple Markov process for the noise at the discrimination point. The error probability of this method i...

In practical communication systems, spurious amplitude and phase effects are normally mutually interrelated. Most semiconductor and thermionic amplifier devices, when driven from their quasilinear region into a saturated state by large amplitude signal changes, impress phase and amplitude changes onto other signals operating within the normally linear region. Practical digital modems are sensitive... View full abstract»
A simple ground clutter model has been analysed using nonlinear methods of power spectral estimation and the performance of these methods has been studied. The methods considered are the maximum entropy method (MEM), the maximum likelihood method (MLM), the least-squares method (LSM), the autoregressive moving average (ARMA) method and Prony's energy spectral-density estimation (PESD). The perform... View full abstract»

The impact of home automation on domestic lifestyles will be as far ranging as was that of factory automation on industry and its benefits will be available to all sectors of society. Home automation will be achieved not with the household robot but with embedded computing power and memory within dozens of pieces of domestic equipment, each of which will communicate with the user and with other eq...

Aims & Scope
Published from 1989-2002, the Electronics & Communication Engineering Journal aimed to inform practising professional engineers who were involved in electronics and communications by providing coverage of new developments in a serious technical, but not in an overformal or academic manner.
Topics covered included: Measurement and instrumentation; circuit design, simulation and CAD; signal and image processing, coding; microwaves, antennas and radio propagation; optoelectronics; TV and sound broadcasting; telecommunication networks; radio and satellite communications; radar, sonar and navigation systems; and electromagnetic compatibility.
