GNSS Spectrums

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

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

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...

To obtain the version of your current nVidia graphics drivers, the easiest way is to download GPU-Z. However in some scenarios, you cant use any other tools, so you have to search manually. By going to the Windows device manager and further into graphic...
Ocean FFT in Matlab

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...
