On PMU Location Selection for Line Outage Detection in Wide-area Transmission Networks
Yue Zhao, Andrea Goldsmith, H. Vincent Poor
The optimal PMU locations to collect voltage phase angle measurements for detecting line outages in wide-area transmission networks are investigated. The problem is established as…
Primary Rate-Splitting Achieves Capacity for the Gaussian Cognitive Interference Channel
Stefano Rini, Ernest Kurniawan, Andrea Goldsmith
The cognitive interference channel models cognitive overlay radio systems, where cognitive radios overhear the transmission of neighboring nodes. Capacity for this channel is not k…
Channel Capacity under Sub-Nyquist Nonuniform Sampling
Yuxin Chen, Andrea J. Goldsmith, Yonina C. Eldar
This paper investigates the effect of sub-Nyquist sampling upon the capacity of an analog channel. The channel is assumed to be a linear time-invariant Gaussian channel, where perf…
Blind Null-space Tracking for MIMO Underlay Cognitive Radio Networks
Alexandros Manolakos, Yair Noam, Andrea J. Goldsmith
Blind Null Space Learning (BNSL) has recently been proposed for fast and accurate learning of the null-space associated with the channel matrix between a secondary transmitter and…
Practical Coding Schemes for Cognitive Overlay Radios
Ernest Kurniawan, Andrea Goldsmith, Stefano Rini
We develop practical coding schemes for the cognitive overlay radios as modeled by the cognitive interference channel, a variation of the classical two user interference channel wh…
Joint Source-Channel Cooperative Transmission over Relay-Broadcast Networks
Deniz Gunduz, Elza Erkip, Andrea Goldsmith +1
Reliable transmission of a discrete memoryless source over a multiple-relay relay-broadcast network is considered. Motivated by sensor network applications, it is assumed that the…
Channel Capacity under General Nonuniform Sampling
Yuxin Chen, Yonina C. Eldar, Andrea J. Goldsmith
This paper develops the fundamental capacity limits of a sampled analog channel under a sub-Nyquist sampling rate constraint. In particular, we derive the capacity of sampled analo…
Spatial MAC in MIMO Communications and its Application to Underlay Cognitive Radio
Yair Noam, Andrea Goldsmith
We propose a learning technique for MIMO secondary users (SU) to spatially coexist with Primary Users (PU). By learning the null space of the interference channel to the PU, the SU…
