A MIMO-OFDM channel estimation scheme utilizing complementary sequences
We present a pilot-assisted method for estimating the frequency selective channel in a MIMO-OFDM system. The pilot sequence is designed using the DFT of the Golay complementary se...

Efficient Run-Time Support for Irregular Task Computations with Mixed Granularities
Many irregular scientific computing problems can be modeled by directed acyclic task graphs (DAGs). In this paper, we present an efficient run-time system for executing general as...
