DOCOMO Beijing Labs Selects MATLAB

MathWorks, a developer of mathematical computing software, has revealed that DOCOMO Beijing Communications Laboratories has adopted MATLAB to develop and verify algorithms for the development of new physical layer mobile communications technologies for standards such as LTE (News - Alert)-A.

The utilization of MATLAB has allowed DOCOMO Beijing Labs to reduce development time by 50 percent compared with its previous C and C++ development methods. Moreover, researchers will be able to rapidly develop new algorithms for link-level and system-level simulations.

“The work at DOCOMO Beijing Labs directly influences the development of future wireless standards worldwide,” said Arun Mulpur, communications, electronics, and semiconductors industry marketing manager at MathWorks, in a statement. “MATLAB has helped these researchers and engineers explore new ideas and theories, develop algorithms and systems, and functionally verify their designs.”

DOCOMO engineers used a simulation frame to verify algorithms developed in MATLAB. The advanced algorithms are built on a transmit-and-receive chain using MATLAB’s Signal Processing Toolbox and Communications System Toolbox.

A press release said the engineers leveraged the Parallel Computing Toolbox to parallelize communications algorithms and scale them without code changes to a 32-core cluster running the MATLAB Distributed Computing Server.

“With MATLAB we spend less time coding and more time developing innovative mobile communications algorithms,” said a research engineer at DOCOMO Beijing Labs. “More importantly, with only minor modifications we can accelerate the simulation of algorithms on our computing cluster to thoroughly evaluate and verify them under a wide range of operating conditions and scenarios.”

Recently, MathWorks announced the release of its MATLAB and Simulink product families. Comprised in this release is the Simulink Code Inspector, which facilitates the review of source code generated from Simulink models.
