Data Transmission Over Networks for Estimation and Control (2009)
Gupta, Vijay, Dana, Amir F., Hespanha, Joao P., Murray, Richard M., Hassibi, Babak
We consider the problem of controlling a linear time invariant process when the controller is located at a location remote from where the sensor measurements are being generated. The communication...

Differentiated rate scheduling for the down-link of cellular systems (2008)
Dana, Amir F., Sharif, Masoud, Vakili, Ali, Hassibi, Babak
We consider the problem of differentiated rate scheduling for the downlink (i.e., multi-antenna broadcast channel), in the sense that the rates required by different users must satisfy certain...

A Practical Scheme for Wireless Network Operation (2007)
Gowaikar, Radhika, Dana, Amir F., Hassibi, Babak, Effros, Michelle
In many problems in wireline networks, it is known that achieving capacity on each link or subnetwork is optimal for the entire network operation. In this paper, we present examples of wireless...
On the Capacity Region of Multi-Antenna Gaussian Broadcast Channels with Estimation Error (2006)
Dana, Amir F., Sharif, Masoud, Hassibi, Babak
In this paper we consider the effect of channel estimation error on the capacity region of MIMO Gaussian broadcast channels. It is assumed that the receivers and the transmitter have (the same)...
On the effect of quantization on performance at high rates (2006)
Gupta, Vijay, Dana, Amir F., Murray, Richard M., Hassibi, Babak
We study the effect of quantization on the performance of a scalar dynamical system in the high rate regime. We evaluate the LQ cost for two commonly used quantizers: uniform and logarithmic and...
On the Power Efficiency of Sensory and Ad Hoc Wireless Networks (2006)
We consider the power efficiency of a communications channel, i.e., the maximum bit rate that can be achieved per unit power (energy rate). For additive white Gaussian noise (AWGN) channels, it is...
Capacity of wireless erasure networks (2006)
Dana, Amir F., Gowaikar, Radhika, Palanki, Ravi, Hassibi, Babak, Effros, Michelle
In this paper, a special class of wireless networks, called wireless erasure networks, is considered. In these networks, each node is connected to a set of nodes by possibly correlated erasure...
On the power efficiency of sensory and ad-hoc wireless networks (2006)
We consider the power efficiency of a communications channel, i.e., the maximum bit rate that can be achieved per unit power (energy rate). For AWGN channels, it is well known that power efficiency...
Differentiated rate scheduling for Gaussian broadcast channels (2005)
Sharif, Masoud, Dana, Amir F., Hassibi, Babak
In this paper, we consider a fading broadcast channel where users have different rate demands. In particular, we assume users are divided into M groups, each group of which requires the same rate,...
Is broadcast plus multiaccess optimal for Gaussian wireless networks? (2004)
Dana, Amir F., Sharif, Masoud, Gowaikar, Radhika, Hassibi, Babak, Effros, Michelle
In this paper we show that "separation"-based approaches in wireless networks do not necessarily give good performance in terms of the capacity of the network. Therefore in optimal design of a...
On the capacity of wireless erasure networks (2004)
Gowaikar, Radhika, Dana, Amir F., Palanki, Ravi, Hassibi, Babak, Effros, Michelle
We determine the capacity of a certain class of wireless erasure relay networks. We first find a suitable definition for the "cut-capacity" of erasure networks with broadcast at transmission and no...
