The use of CORDIC in software defined radios: a tutorial
TL;DR: This article shows how to use CORDIC to implement direct digital synthesizers, AM, PM, and FM analog modulators and ASK, PSK and FSK modulators, up-/down-converters of in-phase and quadrature signals, full mixers for complex signals, and phase detection for synchronizers.
Journal ArticleDOI
Reduced-Complexity Min-Sum Algorithm for Decoding LDPC Codes With Low Error-Floor
TL;DR: This paper proposes a low-complexity min-sum algorithm for decoding low-density parity-check codes where the two-minimum calculation is replaced by one minimum calculation and a second minimum emulation, reducing by this way the decoder complexity.
Journal ArticleDOI
FFT Spectrum Analyzer Project for Teaching Digital Signal Processing With FPGA Devices
TL;DR: The structure and methodology used in the proposed course are oriented to the design and implementation of an fast Fourier transform (FFT) spectrum analyzer, which enables students and engineers to understand and develop complex fixed-point applications.
Journal ArticleDOI
Hardware Architecture of a Gaussian Noise Generator Based on the Inversion Method
TL;DR: A hardware-based Gaussian noise generator with low hardware cost, high generation rate, and high Gaussian tail accuracy is presented, based on a piecewise polynomial approximation of the inverse cumulative distribution function (ICDF).
Journal ArticleDOI
FPGA-implementation of atan(Y/X) based on logarithmic transformation and LUT-based techniques
TL;DR: An architecture for the computation of the atan(Y/X) operation suitable for broadband communications systems where a throughput between 20 and 40MHz is required and a combination of non-uniform segmentation and multipartite LUT technique is proposed for the arctangent of the logarithm approximation.
