Minimum BER beamforming in the RF domain for OFDM transmissions and linear receivers
In this paper, we study transmission schemes for a novel OFDMbased MIMO system which performs adaptive signal combining in radio-frequency (RF). Specifically, we consider the prob...

Degree Fluctuations and the Convergence Time of Consensus Algorithms
We consider a consensus algorithm in which every node in a time-varying undirected connected graph assigns equal weight to each of its neighbors. Under the assumption that the deg...

Block recycling schemes and their cost-based optimization in nand flash memory based storage system
Flash memory has many merits such as light weight, shock resistance, and low power consumption, but also has limitations like the erase-before-write property. To overcome such lim...
