Simulation of Newton’s second law of Motion

Satellites are very important part of modern civilization, they are used for many purposes and each of us is using or at least has used some of their services. I won’t be however talking about the purposes of the satellites today. I would rather spend some time...

FFT Implementation R2 DIT| R4 DIF | R8 DIF

First of all, I would like to point out,that I will not cover the mathematical background beyond the FFT (Fast Fourier Transform), which is in fact just an algorithm of fast calculation of the Discrete Fourier Transform (DFT). I will just concentrate on how the Radix...

GNSS Spectrums

I wil try to cover some basic concepts regarding GNSS signals in this post. I will start with GPS and GALILEO (Which of now is in stage 2 – IOC “Initial Operation Capability” with 10 available Satellites). The problem with these 2 systems is that...

Hamming Codes

Hamming codes are a part of Linear Block Codes. They were invented in 1950 and can repair 1 error or detect 2. The most famous code is probably hamming[7,4]. That is a code with a codeword length of 7, which is carrying 4 data bits and 3 parity bits. Hamming codes can...

GPS Acquisition and L1 Signal Processing

As you may have noticed in some of my previous posts, I have dedicated some time to learn the GPS basics, which I would like to share with you today. Those with a matlab installed on their machine will be of course able to download all the source codes and run them...

Ocean FFT in Matlab

I was always amazed how fantastic was the Ocean simulation from nVidia (Its a part of the CUDA toolkit). I did not understand how was it working, so I searched and in fact found many examples on the internet. All of the ocean wave animations use the statistics model...

Got an interesting ongoing technical project, job position or just a specific problem you would like to solve ? Or do you need a teammate to help develop a specific CUDA / C / C++ / .net / Java / Matlab application and or algorithm? Catch me on [email protected] :) I would love to learn new things, though I am currently interested in GPGPU, GNSS, Wireless Comunications, Image Processing and Atmosferic Science.
