Optimal Throughput-Diversity-Delay Tradeoff in MIMO ARQ Block-Fading Channels
In this paper, we consider an automatic-repeat-request (ARQ) retransmission protocol signaling over a block-fading multiple-input, multiple-output (MIMO) channel. Unlike previous ...

Tightness of capacity bounds in correlated MIMO systems with channel estimation error
We consider a point-to-point, correlated and block fading multiple antenna channel where the receiver has a noisy channel estimation and the transmitter has the statistics of the c...

GAME-theory-based cross-layer optimization for wireless DS-CDMA visual sensor networks
We propose a game-theory-based cross-layer optimization scheme for wireless Direct Sequence Code Division Multiple Access (DSCDMA) visual sensor networks. The scheme uses the Nash...

On the performance of multicarrier DS-CDMA with imperfect power control and variable spreading factors
Multicarrier direct-sequence code-division multiple access (MC-DS-CDMA) becomes an attractive technique for the future fourth-generation (4G) wireless system because it can flexibl...

Joint Power Scheduling and Estimator Design for Sensor Networks Across Parallel Channels
—This paper addresses the joint estimator and power optimization problem for a sensor network whose mission is to estimate an unknown parameter. We assume a two-hop network where...
