Communications

• The UTRA FDD Blockset

  is a library of Simulink blocks that can be combined to create models of the UTRA W-CDMA physical layer. Using this blockset, you can rapidly construct a wide variety of transmitter reference models. Because the models have already been verified, they provide an independent reference against which proprietary designs may be tested. Multiple Access Communications Ltd. www.macltd.com.

• WLAN Toolbox for MATLAB

  contains buildingblock modules that are needed to generate, demodulate, and decode high-speed WLAN waveforms compliant with IEEE Standard 802.11a/b/g. It provides users with the flexibility to prototype customized links for their own design tasks, such as equalizer and tracking loops. This toolbox consists mainly of MATLAB M-files and DLL files. CommAccess Technologies www.commaccess.com.

• OptSim

  is a modeling and simulation environment supporting the performance evaluation and design of the transmission level of optical communication systems. It includes a library of simulation algorithms with more than 400 of the most widely used optical and optoelectronic components. The OptSim interface to MATLAB enables OptSim users to run MATLAB routines that fully interact with the OptSim data structure, either for pre- and post-processing or for cosimulation. RSoft Design Group, Inc. www.rsoftdesign.com.

• VPItransmissionMaker™ WDM

  is a comprehensive design environment that automatically synthesizes and analyzes the physical aspects of WDM transmission systems. A cable access version is also available for the design of HFC, DOCSIS, and emerging technologies for TV, data, and IP. A MATLAB interface provides additional functionality, including the ability to model the electrical path of a communication link. VPIphotonics www.vpiphotonics.com.

• The Huron Digital Audio Convolution Workstation

  is a rack-mounting industrial PC fitted with a combination ISA bus and Huron bus backplane. These systems can be used for digital audio applications, including advanced acoustic measurement and analysis, rapid prototyping and implementation of DSPbased audio tools, measuring and emulating acoustic environments, and real-time VR simulations. The Huron MATLAB interface enables the control of VRack software running on the Huron Audio DSP System via MATLAB commands and scripts. Lake Technology Limited www.laketechnology.com.

Academia

• 3-D Crane

  is a laboratory system imitating a computer-controlled industrial gantry crane that can be as large as 3x3x3 meters and can move independently in three perpendicular directions. The 3- D Crane control system is a useful tool for research and teaching at technical universities in the field of automatic control and mechatronic systems. 3- D Crane uses MATLAB and Simulink to develop and run the controllers. Simulink, Real-Time Workshop, and Real-Time Windows Target generate real-time controllers. InTeCo Ltd. www.inteco.com.pl.

• Digital Pendulum Control System 33-005

  is a contemporary version of the classic control problem. It is large enough to be convincing, durable enough to survive the hazards of a student laboratory, and open enough for design studies. A twin-arm pendulum pivots freely on a small cart running on an elevated two-rail track. An extensive MATLAB toolbox is provided, as well as transfer function and state space model specifications in Simulink. Feedback, Inc. www.fbk.com.

• The CE150 Helicopter, CE151 Ball & Plate, and CE152 Magnetic Levitation Models

  are educational control models designed to provide realistic laboratory versions of practical, industrial situations. These can be controlled in real time from within the MATLAB and Simulink environment using Real-Time Windows Target. All systems are controlled by a PC and include comprehensive technical and educational support materials. TecQuipment Limited www.tq.com.

• Experimental Control System Workstations

  provide for the study of feedback control systems. The systems are used extensively in undergraduate control systems laboratories as well as graduate research and industrial motion control training. MATLAB is used in the dynamic analysis of the plants, in system identification and control model generation, and in control system design and analysis. These applications can be used in conjunction with Real-Time Workshop and Simulink to provide a real-time Simulink environment for control and operation of ECP systems. Educational Control Products www.ecpsystems.com.

• TIMS Interactives

  is a set of MATLAB programs that interactively combines equations, text, and graphics to help a student learn more about telecommunications. TIMS Interactives enables a student to study the math related to many different issues in telecommunications in a real-time, interactive MATLAB environment. Emona Instruments Pty. Ltd. www.qpsk.com.

• Feedback Control Experiments

  are robust, durable, and modular systems that enables you to reconfigure the same plant to obtain various experiments. Experiments include the Inverted Pendulum, the Ball and Beam, the Seesaw/Pendulum MIMO experiment, and the Helicopter. All systems are equipped with quickconnect cabling, source code in C, handbooks, system modeling, and control system design files written in Maple, MATLAB, and Simulink.
