DMT optimality of LR-aided linear decoders for a general class of channels, lattice designs, and system models
The work identifies the first general, explicit, and non-random MIMO encoder-decoder structures that guarantee optimality with respect to the diversity-multiplexing tradeoff (DMT),...

Directly lower bounding the information capacity for channels with I.I.D.deletions and duplications
We directly lower bound the information capacity for channels with i.i.d. deletions and duplications. Our approach differs from previous work in that we focus on the information ca...

Power-controlled feedback and training for two-way MIMO channels
Most communication systems use some form of feedback, often related to channel state information. The common models used in analyses either assume perfect channel state information...

Performance bounds for erasure, list and decision feedback schemes with linear block codes
A message independence property and some new performance upper bounds are derived in this work for erasure, list and decision-feedback schemes with linear block codes transmitted ...

Two-dimensional constrained coding based on tiling
A new variable-rate coding technique is presented for two-dimensional constraints. For certain constraints, such as the (0, 2)-RLL, (2, )-RLL, and the "no isolated bits" ...

The power of convex relaxation: near-optimal matrix completion
This paper is concerned with the problem of recovering an unknown matrix from a small fraction of its entries. This is known as the matrix completion problem, and comes up in a gr...

Pairwise intersession network coding on directed networks
When there exists only a single multicast session in a directed acyclic/cyclic network, the existence of a network coding solution is characterized by the classic min-cut/max-flow ...

Secure communications with insecure feedback: breaking the high-SNR ceiling
A multiple-antenna Gaussian wiretap channel in which the number of antennas at the source is not greater than that at the eavesdropper is considered. Without feedback, the secrecy...
