This paper presents a novel multiple antenna transmission scheme that depends on channel state information.

We present multiple antenna transmitter optimization (i.e., spatial prefiltering) schemes that are based on linear transformations and transmit power optimization (keeping average transmit power co

Clustered DFT-S-OFDM, which is an extension of SCFDMA, has been accepted as the uplink multiple access scheme for LTE-Advanced.

We investigate the use of multiple antennas in the downlink of a high data reate (HDR) system where the base station transmits to a single user at a time on 16 CDMA channels.

Multiple antennas can greatly increase the data rate and reliability of a wireless communication link in a fading environment, but the practical success of using multiple antennas depends crucially

No abstract. Viewgraph material only.

We investigate the use of multiple antennas at the transmitter and multiple antennas and multi-user decorrelating detectors at the receivers for providing high-speed data on the downlink of cellula

We propose a more efficient Automatic Retransmission reQuest (ARQ) scheme for MIMO systems with multiple transmit and multiple receive antennas.

We propose a more efficient Automatic Retransmission reQuest (ARQ) for MIMO systems with multiple transmit and multiple receive antennas.

We report for the first time the use of two types of Er3+ planar optical waveguide amplifiers in 77 channel CATV fiber links.
