Optimizing Orthogonal Multiple Access based on Quantized Channel State Information

Antonio G. Marques, Georgios B. Giannakis, Javier Ramos

The performance of systems where multiple users communicate over wireless fading links benefits from channel-adaptive allocation of the available resources. Different from most exi…

Performance of Hybrid-ARQ in Block-Fading Channels: A Fixed Outage Probability Analysis

Peng Wu, Nihar Jindal

This paper studies the performance of hybrid-ARQ (automatic repeat request) in Rayleigh block fading channels. The long-term average transmitted rate is analyzed in a fast-fading s…

Delay Constrained Scheduling over Fading Channels: Optimal Policies for Monomial Energy-Cost Functions

Juyul Lee, Nihar Jindal

A point-to-point discrete-time scheduling problem of transmitting information bits within hard delay deadline slots is considered assuming that the underlying energy-bit co…

Energy-efficient Scheduling of Delay Constrained Traffic over Fading Channels

Juyul Lee, Nihar Jindal

A delay-constrained scheduling problem for point-to-point communication is considered: a packet of bits must be transmitted by a hard deadline of slots over a time-varying…

On Certain Large Random Hermitian Jacobi Matrices with Applications to Wireless Communications

Nathan Levy, Oren Somekh, Shlomo Shamai +1

In this paper we study the spectrum of certain large random Hermitian Jacobi matrices. These matrices are known to describe certain communication setups. In particular we are inter…

Analysis of Fixed Outage Transmission Schemes: A Finer Look at the Full Multiplexing Point

Peng Wu, Nihar Jindal

This paper studies the performance of transmission schemes that have rate that increases with average SNR while maintaining a fixed outage probability. This is in contrast to the c…
