Improving the quality of ring oscillator PUFs on FPGAs
Physical Unclonable Functions (PUFs) based on Ring Oscillators (ROs) are a promising primitive for FPGA security. However, the quality of their implementation depends on several d...

A Novel Graph-Based Suboptimal Multiuser Detector for FDM-CPM Transmissions
We consider a frequency division multiplexed (FDM) system where each user employs a continuous phase modulation (CPM), serially concatenated with an outer code through an interleav...

A hybrid compressed sensing algorithm for sparse channel estimation in MIMO OFDM systems
Due to multipath delay spread and relatively high sampling rate in OFDM systems, the channel estimation is formulated as a sparse recovery problem, where a hybrid compressed sensi...

Detecting low-rate periodic events in Internet traffic using renewal theory
In our previous work [1, 2] we studied detection of anomalies in packet arrival times for computer networks, most detection of denialof-service (DoS) attacks in Internet traffic....
