SERI standardized on MathWorks tools to develop their next-generation wireless technologies. They’re also migrating all their existing algorithms to Simulink to facilitate their reuse in future development initiatives.
With limited experience with Simulink, SERI worked with MathWorks Consulting to accelerate this transition.
The ATG uses Simulink to develop algorithms and to create models of 4G communications systems. They use Communications System Toolbox™ and DSP System Toolbox™ to speed their model development.
The team also uses Simulink to integrate C and C++ code into their simulations. By integrating custom code, they can include algorithms from other consortium partners and their own proprietary optimized implementations of algorithms once the generic models are complete. Their own algorithms will ultimately become part of SERI’s patent portfolio.
SERI uses MATLAB® for statistical analysis and graphical plotting to better visualize and understand system behavior and experimental data. They generate sets of BER curves for their Simulink models with MATLAB scripts to understand the effect of variables and to quantify the merits of competing technologies. For multiple-carrier code division multiple access (MC-CDMA), this enables them to assess the robustness of various detection algorithms to multiple access interference.
During the calibration phase of the project, in which all partners contributing to physical layer research compare their results using a set of predetermined scenarios, SERI relies on Simulink and Communications System Toolbox.
The team also uses DSP System Toolbox to develop advanced encoding algorithms, such as low-density parity check (LDPC) coding.
The ATG researchers use Simulink to develop new interference-cancellation algorithms using soft information obtained from several coding schemes and LDPC. After obtaining reference data from single- and multi-user detection scenarios, the researchers apply advanced channel coding to implement the interference-cancelling loop.
The ATG is approaching completion of the entire MC-CDMA assessment at the physical level.
