Floating- to fixed-point MATLAB algorithm conversion for FPGAs

In a recent survey conducted by AccelChip Inc. (recently acquired by Xilinx), 53% of the respondents identified floating- to fixed-point conversion as the most difficult aspect of implementing an ...

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 ...

Fast fixed-point algorithm for blind separation of nonlinear autocorrelation and non-Gaussian sources

Abstract: Blind source separation (BSS) problem is often solved by using only one statistical property of original sources. In this work, a method combines non-Gaussianity and nonlinear ...
