Clustering with Lower Bound on Similarity
We propose a new method, called SimClus, for clustering with lower bound on similarity. Instead of accepting k the number of clusters to find, the alternative similarity-based app...

Multiantenna spectrum sensing: Detection of spatial correlation among time-series with unknown spectra
One of the key problems in cognitive radio (CR) is the detection of primary activity in order to determine which parts of the spectrum are available for opportunistic access. This...

Combining Parallel Sequence Spread Spectrum (PSSS) with OFDM - Concept and Simulation Results
—In this paper, we present a novel multi-carrier spread spectrum (MCSS) system which uses Parallel Sequence Spread Spectrum (PSSS) as its spreading transform. This technique call...
