General Purpose
The Signal Processing Information Base (SPIB) serves as a repository of datasets for both signal processing researchers and applications engineer, seeking to provide suitable ways for testing algorithms, systems, and applications under more realistic operating conditions. Particularly, SPIB contains datasets (arising from real-world measurements) and links to other repositories, all of which are relevant to research and development in signal processing.
If you need assistance, wish to report a problem, or want to update information, send an email to spib@linse.ufsc.br.
Data repository has been reformatted into Matlab (.mat) format; however, please feel free to contact us if you need other file-types.
Historical Remarks
Dating back to 1993, the Signal Processing Information Base (SPIB) was originally a project sponsored by the Signal Processing Society (SPS) and the National Science Foundation (NSF) having the goal to provide a public repository of information related to signal processing researches. During approximately 20 years, this website was hosted at Rice University under the supervision of Dr. Don H. Johnson (the creator of this project). Recently, when such website becomes unavailable, we have contacted Dr. Johnson aiming to get a full backup of the website content (for further reference). Kindly, Dr. Johnson provided this backup, which was used to make all that content available again. Currently, the SPIB is been maintained by Circuits and Signal Processing Laboratory (LINSE) at Federal University of Santa Catarina.
