Cross-Layer combining of adaptive Modulation and coding with truncated ARQ over wireless links
We developed a cross-layer design which combines adaptive modulation and coding at the physical layer with a truncated automatic repeat request protocol at the data link layer, in order to maximizeExpand

Queuing with adaptive modulation and coding over wireless links: cross-Layer analysis and design
Assuming there are always sufficient data waiting to be transmitted, adaptive modulation and coding (AMC) schemes at the physical layer have been traditionally designed separately from higher layers.Expand

Multicarrier Communication Over Underwater Acoustic Channels With Nonuniform Doppler Shifts
Underwater acoustic (UWA) channels are wideband in nature due to the small ratio of the carrier frequency to the signal bandwidth, which introduces frequency-dependent Doppler shifts. In this paper,Expand

Achieving the Welch bound with difference sets
Consider a codebook containing N unit-norm complex vectors in a K-dimensional space. In a number of applications, the codebook that minimizes the maximal cross-correlation amplitude (I/sub max/) isExpand

Sparse channel estimation for multicarrier underwater acoustic communication: From subspace methods to compressed sensing
In this paper, we present various channel estimators that exploit the channel sparsity in a multicarrier underwater acoustic system, including subspace algorithms from the array precessingExpand

Chip-interleaved block-spread code division multiple access
A novel multiuser-interference (MUI)-free code division multiple access (CDMA) transceiver for frequency-selective multipath channels is developed. Relying on chip-interleaving and zero paddedExpand

Aqua-Sim: An NS-2 based simulator for underwater sensor networks
In this paper, we present a network simulator, Aqua-Sim, for underwater sensor networks. Aqua-Sim is based on NS-2, one of the most widely used network simulators, and it follows object-orientedExpand

Optimal transmitter eigen-beamforming and space-time block coding based on channel mean feedback
Optimal transmitter designs obeying the water-filling principle are well-documented; they are widely applied when the propagation channel is deterministically known and regularly updated at theExpand

The challenges of building mobile underwater wireless networks for aquatic applications
The large-scale mobile underwater wireless sensor network (UWSN) is a novel networking paradigm to explore aqueous environments. However, the characteristics of mobile UWSNs, such as lowExpand
