Energy-Efficiency Gains of Caching for Interference Channels
Jad Hachem, Urs Niesen, Suhas Diggavi
This paper initiates the study of energy-efficiency gains provided by caching. We focus on the cache-aided Gaussian interference channel in the low-SNR regime. We propose a strateg…
An Information-Theoretic Analysis of Deduplication
Urs Niesen
Deduplication finds and removes long-range data duplicates. It is commonly used in cloud and enterprise server settings and has been successfully applied to primary, backup, and ar…
Degrees of Freedom of Cache-Aided Wireless Interference Networks
Jad Hachem, Urs Niesen, Suhas Diggavi
We study the role of caches in wireless interference networks. We focus on content caching and delivery across a Gaussian interference network, where both transmitters and receiver…
A Layered Caching Architecture for the Interference Channel
Jad Hachem, Urs Niesen, Suhas Diggavi
Recent work has studied the benefits of caching in the interference channel, particularly by placing caches at the transmitters. In this paper, we study the two-user Gaussian inter…
Joint Crosstalk-Avoidance and Error-Correction Coding for Parallel Data Buses
Urs Niesen, Shrinivas Kudekar
Decreasing transistor sizes and lower voltage swings cause two distinct problems for communication in integrated circuits. First, decreasing inter-wire spacing increases interline…
Cache-Aided Interference Channels
Mohammad Ali Maddah-Ali, Urs Niesen
Over the past decade, the bulk of wireless traffic has shifted from speech to content. This shift creates the opportunity to cache part of the content in memories closer to the end…
