Analysis of the pilot contamination effect in very large multicell multiuser MIMO systems for physical channel models
We consider multicell multiuser MIMO systems with a very large number of antennas at the base station. We assume that the channel is estimated by using uplink training sequences, ...

Coding for High-Density Recording on a 1-D Granular Magnetic Medium
In terabit-density magnetic recording, several bits of data can be replaced by the values of their neighbors in the storage medium. As a result, errors in the medium are dependent ...

A robust asynchronous multiuser STBC-OFDM transmission scheme for frequency-selective channels
Abstract--In this paper, we propose a robust STBC transmission scheme to combat timing synchronization errors over frequency-selective multiple-access channels. We start by derivin...

A Channel that Heats Up
Motivated by on-chip communication, a channel model is proposed where the variance of the additive noise depends on the weighted sum of the past channel input powers. For this chan...
