Unitary Precoding Techniques Based on Transmit-MRC for MIMO Wireless Systems
— This paper proposes a low complexity unitary precoding scheme for multiple-input multiple-output (MIMO) systems. The singular-value decomposition (SVD) based transmission is ca...

Secure FPGA circuits using controlled placement and routing
In current Field-Programmable-Logic Architecture (FPGA) design flows, it is very hard to control the routing of submodules. It is thus very hard to make an identical copy of an ex...
