Talk Title: Transmit Antenna Selection in Underlay Spectrum Sharing: Role of Interference Constraint, Channel State Information, and Power Adaptation
Series: Center for Cyber-Physical Systems and Internet of Things
Abstract: Spectrum sharing mitigates the scarcity of radio spectrum by enabling different classes of users to utilize spectrum together without exclusively and inefficiently allocating the spectrum to just one class of users. In the underlay paradigm of spectrum sharing, a low priority secondary user can transmit concurrently in the same spectrum as a high priority primary user but must ensure that the interference it causes to the primary receiver is constrained. We investigate transmit antenna selection to improve the performance of such interference-constrained underlay spectrum sharing systems. It exploits the spatial diversity afforded by multiple antennas but with much less hardware.
We characterize the optimal antenna selection and power adaptation rules for several stochastic interference constraints. The fact that the choice of the antenna at the secondary transmitter is driven not just by the channel gains from it to the secondary receiver's antennas, but also by the interference it causes to the primary receiver makes the class of problems that we study interesting and novel. The optimal antenna selection and power adaptation rules that we arrive at differ significantly from the ad hoc approaches pursued in the literature and lead to markedly lower symbol error rates. They bring out the significant and varied influence the triumvirate of interference constraint, channel state information, and power adaptation has on antenna selection.

Talk Title: Context-Aware Coding for Computing Memories
Series: Center for Cyber-Physical Systems and Internet of Things
Abstract: Error correction and detection are the core components of all modern memory systems. Current computing memory systems use simple coding schemes to simultaneously meet the resiliency and latency requirements. In this talk, we review our recent results on context-aware coding for computing memories, an approach that explicitly takes into account various intrinsic side information for improved robustness to faults. We discuss both error correction and detection, codes' theoretical properties, and provide examples of how these solutions can be implemented in practice. We explicitly describe the special case of the error localization codes. We also discuss promising future directions, connections with classical information theoretic concepts, and other applications. Joint work with C. Schoeny, M. Gottscho, I. Alam, and P. Gupta.
