Estimation of Sparse MIMO Channels with Common Support

Martin Vetterli, Ali Hormati, Yann Barbotin

We consider the problem of estimating sparse communication channels in the MIMO context. In small to medium bandwidth communications, as in the current standards for OFDM and CDMA communication systems (with bandwidth up to 20 MHz), such channels are indiv ...

Memory Organization and Data Layout for Instruction Set Extensions with Architecturally Visible Storage

Paolo Ienne, Yusuf Leblebici, Philip Brisk, Panagiotis Athanasopoulos

Present application specific embedded systems tend to choose instruction set extensions (ISEs) based on limitations imposed by the available data bandwidth to custom functional units (CFUs). Adoption of the optimal ISE for an application would, in many cas ...

Many Networks-on-Chip (NoC) applications exhibit one or more critical traffic flows that require hard Quality of Service (QoS). Guaranteeing bandwidth and latency for such real time flows is crucial. In this paper, we present novel methods to efficiently c ...

Bandwidth-Constrained Mapping of Cores onto NoC Architectures

Giovanni De Micheli, Srinivasan Murali

We address the design of complex monolithic systems, where processing cores generate and consume a varying and large amount of data, thus bringing the communication links to the edge of congestion. Typical applications are in the area of multi-media proces ...

We propose resource allocation strategies for a class of wireless networks with a clustering protocol. The nodes are assumed stationary and establish connections with the master node according to a priority scheme that relates to their distances from the m ...
