How to use arbitrary bit-widths in C++/C-based algorithm designs

Developing fixed-point algorithm descriptions used to require tradeoffs between design functionality, modeling of numerical precision, and validation (simulation) speed. Now, a new class of C++ ...

Complex Fixed-Point ICA Algorithm for Separation of QAM Sources using Gaussian Mixture Model

Abstract: We introduce a fixed-point algorithm, the complex QAM (C-QAM) algorithm, for separation of quadrature amplitude modulated (QAM) sources through independent component analysis. The algorithm ...
