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 ...

Feedback-based coding algorithms for broadcast erasure channels with degraded message sets

Christina Fragouli, Shirin Saeedi Bidokhti

We consider single-hop broadcast packet erasure channels (BPEC) with degraded message sets and instantaneous feedback regularly available from all receivers, and demonstrate that the main principles of the virtual-queue-based algorithms in [1], which were ...

A novel low complexity data demodulation algorithm for pulse position modulation

Pierre-André Farine, Cyril Botteron

In this paper, a low complexity data demodulation algorithm is proposed that requires time of arrival information of the received signal exclusively. As an application example, the algorithm is applied to an ultra-wideband impulse radio communication syste ...

A Distributed Interleaving Scheme for Efficient Access to WideIO DRAM Memory

Giovanni De Micheli, Luca Benini, Ciprian Seiculescu

Achieving the main memory (DRAM) required bandwidth at ac- ceptable power levels for current and future applications is a ma- jor challenge for System-on-Chip designers for mobile platforms. Three dimensional (3D) integration and 3D stacked DRAM mem- ories ...
