About IT++

IT++ is a C++ library of mathematical, signal processing and communication classes and functions. Its main use is in simulation of communication systems and for performing research in the area of communications. The kernel of the library consists of generic vector and matrix classes, and a set of accompanying routines. Such a kernel makes IT++ similar to MATLAB or GNU Octave.

The IT++ library originates from the former department of Information Theory at the Chalmers University of Technology, Gothenburg, Sweden. Because the library is coded in C++, the name IT++ seemed like a good idea at the time. While departments come and go, IT++ have developed a life of its' own and is now released under the terms of the GNU General Public License (GPL) for you to enjoy.

IT++ is being developed and widely used by researchers who work in the area of communications, both in the industry and at universities. In 2005, 2006 and 2007, IT++ was developed as a part of the European Network of Excellence in Wireless Communications (NEWCOM).

IT++ makes an extensive use of existing open-source or commercial libraries for increased functionality, speed and accuracy. In particular BLAS, LAPACK and FFTW libraries can be used. Instead of the reference BLAS and LAPACK implementations, some optimized platform-specific libraries can be used as well, i.e.:

  • ATLAS (Automatically Tuned Linear Algebra Software) - includes optimised BLAS and a limited set of LAPACK routines
  • MKL (Intel Math Kernel Library) - includes all required BLAS, LAPACK and FFT routines (FFTW not required)
  • ACML (AMD Core Math Library) - includes BLAS, LAPACK and FFT routines (FFTW not required)

It is possible to compile and use IT++ without any of the above listed libraries, but the functionality will be reduced.

IT++ should work on GNU/Linux, Sun Solaris, Microsoft Windows (with Cygwin, MinGW/MSYS or Microsoft Visual C++) and Mac OS X operating systems.
