A fast algorithm for creating time-frequency representations based on a special case of the short-time Fourier transform (STFT) is presented. The algorithm is extended with the method known as time-frequency reassignment. This approach makes time-frequency reassignment well suited for real-time implementations.
This work deals with off-loading some time critical parts in the process of performing intrusion detection from software to reconfigurable hardware (FPGA). Signatures of known attacks must typically be compared to high speed network traffic, and string matching becomes a bottleneck. Content Addressable Memories (CAMs) are known to be fast string matchers,… (More)
I would first of all like to thank my advisor Matthew G. Parker for his guidance and help on my thesis. His excellent guidance has been a significant asset to this thesis. I would also like to thank my fellow students and friends for their help, support and understanding through the process of this thesis; Finally, I would like to thank my girlfriend… (More)
