Frequency Offset Tracking for OFDM Systems via Scattered Pilots and Virtual Carriers
— In this paper, we propose a new carrier frequency offset (CFO) tracking algorithm for orthogonal frequency division multiplexing (OFDM) systems. Assuming that the channel remai...

Cryptanalysis of MDC-2
We provide a collision attack and preimage attacks on the MDC-2 construction, which is a method (dating back to 1988) of turning an n-bit block cipher into a 2n-bit hash function. ...
