Improved iterative detection and achieved throughputs of OFDM systems under imperfect channel estimation
Abstract--Assuming imperfect channel estimation, we propose an improved detector for orthogonal frequency-division multiplexing (OFDM) systems over a frequency-selective fading cha...

Interference Suppression Through Adaptive Subset Antenna Transmission in Interference Limited MIMO Wireless Environments
Abstract— We consider spatially multiplexed MIMO transmission in the presence of co-channel interference with subset transmit antenna selection. Several algorithms for antenna se...

Adaptive Channel Reuse in Cellular Systems
Abstract— In cellular systems a large reuse distance reduces cochannel interference while a small reuse distance increases bandwidth allocated to each cell. The optimal reuse dis...

Generalized Capacity and Source-Channel Coding for Packet Erasure Channels
— We study the transmission of a stationary ergodic Gaussian source over a packet erasure channel, which is a composite channel with degraded states. A broadcast channel code can...

Characterizing multiplexing and diversity in visual MIMO
—Mobile optical wireless has so far been limited to very short ranges for high data rate systems. It may be feasible to overcome the data rate limitations over large transmission...
