Advanced Technology Research

Communication science and technology focuses on advanced algorithm research, protocol development and platform prototyping for next generation systems. The MATLAB® and Simulink® family of products offers a rich environment for researchers to rapidly explore and accelerate the development of communications research. Typical areas of research include:

• ultra wideband radio
• multi-user detection
• multiple access interference cancellation
• smart antennas
• waveform design
• terabit optical networking
• and software defined radio

Analysis and Algorithm Development
MATLAB provides a high-level array programming language that enables engineers and scientists to create and apply algorithms and technical concepts in a fraction of the time it would take to program in C/C++, Fortran, or other traditional programming languages. Toolboxes written by leading researchers and engineers from around the world supplement MATLAB with application-specific functionality for signal processing, statistics, control design, and optimization.

Modeling and Simulation
MATLAB and Simulink products provide an environment for creating accurate, mathematical models. The graphical, block-diagram paradigm of Simulink lets you drag-and-drop pre-defined modeling elements into a common model and connect them to create models of systems. As communications systems increase in the number of concurrent activities and overall complexity, the ability to investigate at multiple levels of abstraction has made the MathWorks tools the de facto standard for communications research.

Proof of Concept
Many R&D projects require a proof of concept or rapid prototype. Often, these hardware solutions are not built for production. However, they need to be based on readily available reprogrammable and reconfigurable targets to ensure cost-effective and timely iterations. The MathWorks has partnered with Xilinx, Texas Instruments, and Altera to enable easy and rapid deployment from Simulink models to targets that researchers can use for implementation.

Data Acquisition
MATLAB provides a flexible and easy-to-use environment for acquiring and analyzing data from lab work, interoperating tests, or fieldwork. MathWorks products provide a complete set of tools for analog and digital I/O from a variety of the leading PC-compatible data acquisition hardware manufacturers. Engineers can configure their external hardware devices, read data into MATLAB for analysis, or send data out to lab instruments.
