DOCOMO Beijing taps MATLAB to reduce development time of mobile communications technology

By Telecom Lead Team: MathWorks, A developer of mathematical computing
software, announced that DOCOMO Beijing Communications Laboratories (DOCOMO
Beijing Labs) is using MATLAB to develop and verify algorithms for the
development of new physical layer mobile communications technologies for
advanced standards such as LTE-A.

The adoption of MATLAB enables
DOCOMO Beijing Labs to cut development time by 50 percent compared with its
previous C and C++ development methods. MATLAB also allowed researchers to
rapidly develop new algorithms for link-level and system-level simulations.

With MATLAB we spend less time
coding and more time developing innovative mobile communications algorithms.
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,”
said a
lead research engineer at DOCOMO Beijing Labs. 

DOCOMO Beijing Labs relies on Monte
Carlo simulations that test a range of scenarios and parameter values for
dozens of base stations and hundreds of mobile devices. The researchers need to
perform multiple simulations that are computationally intensive and take weeks
to run on a single computer.

Parallel Computing Toolbox and
MATLAB Distributed Computing Server eased the task of distributing simulations
on their cluster and aggregating the results, helping quickly compare the
performance of different algorithms, assess robustness in poor channel
conditions, and evaluate throughput across the network and at the cell edge.

MATLAB helps researchers reduce the
time for the completion of extensive simulations from weeks to hours. This
speed up has helped to verify more than four times the test cases, parameter
settings, and operating scenarios than was previously possible.

MATLAB has helped these researchers
and engineers explore new ideas and theories, develop algorithms and systems,
and functionally verify their designs,” said Arun Mulpur, communications,
electronics, and semiconductors industry marketing manager at MathWorks. 

MathWorks recently announced a
new version of SimPowerSystems that offers a stronger connection to Simscape
and other physical modelling products in the Simulink family.
