A few months ago I wrote about the Karhunen-Loève Transform (KLT) which could be an interesting alternative for continuous wavelet transforms. I almost forgot about that topic, but today I stumbled over it again. Thus I applied it to my…

Most of my real-time stuff (mainly signal processing) runs on the GPU and I really like CUDA because it is as simple as C or C++ but allows you to tune your graphic card to get the maximum performance you…

Today I stumbled over this interesting paper which describes the usage of the Karhunen-Loève Transform (KLT) for (weak) signal detection in time-series. Although there are many similarities with wavelet analysis, the KLT seems to be less computationally demanding (but its…

Driven by the curiosity for GNOME 3.0 and a little bit fed up with the Ubuntu installation on my GPU laptop I decided to install F15 on that machine. All my other PC’s are running F12 or F13, which are…

After more than four years of keeping my homepage in pure HTML I switched over to Drupal to manage hobiger.org. This will not affect the blog, which will still be available under this address and will continue to run on…

The Generic Mapping Tools (GMT) are a convenient software package for displaying data on a large variety of map projections. Until now data could be converted into GMT native (i.e. NetCDF) format and then output to postscript. With the announcement…

When you have a huge number of files which you want to add to a tar archive you will be usually restricted by the ARG_MAX variable. Of course you could increase that value, but it usually goes along with a…

I am now writing code for NVIDIA GPUs based on CUDA for almost three years. Every two or three months I am thinking to purchase an ATI card and compare its performance to one of the latest NVIDIA cards (e.g.…

After modifying some of the UHD code I finally got a program which reads data from two USRP2s which are synced by a MIMO cable and which stream data via a single Ethernet port. The source code for can be…
