Detecting and blocking P2P botnets through contact tracing chains
: Peer-to-peer (P2P) botnets have recently become serious security threats on the internet. It is difficult to detect the propagation of P2P botnets by isolated monitoring on indiv...

On perfect channel identifiability of semiblind ML detection of orthogonal space-time block coded OFDM
This paper considers maximum-likelihood (ML) detection of orthogonal space-time block coded OFDM (OSTBC-OFDM) systems without channel state information. Our previous work has show...
