چکیده

The diversity-multiplexing tradeoff (DMT) for interference networks, such as the interference channel, the X channel, the Z interference channel and the Z channel, is analyzed. In particular, we investigate the impact of rate-splitting and channel knowledge at the transmitters. We also use the DMT of the Z channel and the Z interference channel to distill insights into the “loud neighbor” problem for femto-cell networks.

Multi-hop Cooperative Wireless Networks: Diversity Multiplexing Tradeoff and Optimal Code Design

In this paper, we consider single-source, single-sink (ss-ss) multi-hop relay networks, with slow-fading Rayleigh links and single-antenna relay nodes operating under the half-duplex constraint. We present protocols and codes to achieve the optimal diversity-multiplexing tradeoff (DMT) of two classes of networks. Networks belonging to the first class can be viewed as the union of K node-disjoin...

A Diversity-Multiplexing-Delay Tradeoff of ARQ Protocols in The Z-interference Channel

In this work, we analyze the fundamental performance tradeoff of the single antenna Automatic Retransmission reQuest (ARQ) Z-interference channel (ZIC). Specifically, we characterize the achievable three-dimensional tradeoff between diversity (reliability), multiplexing (throughput), and delay (maximum number of retransmissions) of two ARQ protocols: A non-cooperative protocol and a cooperative...

Space-time Codes With Good Successive Interference Cancellation Amiable Multiplexing-Diversity Tradeoff

In this work, we propose two high-rate quasiorthogonal space-time coding (STC) schemes which are designed in conjunction with the successive interference cancellation (SIC) based receiver. The symbols of the proposed STC are of judiciously designed diversity order which can be effectively exploited by the SIC based receiver to cancel interference as well as to obtain diversity gain. The propose...

Space-time codes achieving the DMD tradeoff of the MIMO-ARQ channel

For the quasi-static, Rayleigh-fading multiple-input multiple-output (MIMO) channel with transmit and receive antennas, Zheng and Tse showed that there exists a fundamental tradeoff between diversity and spatial-multiplexing gains, referred to as the diversity–multiplexing gain (D-MG) tradeoff. Subsequently, El Gamal, Caire, and Damen considered signaling across the same channel using an -round...
