Active MIMO Sensing: Optimality Conditions and Exploration-Exploitation Tradeoff
Nadim Ghaddar, Kareem M. Attiah, Wei Yu
This paper develops an active sensing framework for designing the transmit and receive beamformers of a multiple-input multiple-output (MIMO) radar system with a limited number of…
Low-Complexity Coding Techniques for Cloud Radio Access Networks
Nadim Ghaddar, Lele Wang
The problem of coding for the uplink and downlink of cloud radio access networks (C-RAN's) with users and relays is considered. It is shown that low-complexity coding schem…
Noisy Computing of the Threshold Function
Ziao Wang, Nadim Ghaddar, Banghua Zhu +1
Let denote the -out-of- threshold function: given input Boolean variables, the output is if and only if at least of the inputs are . We conside…
Noisy Computing of the and Functions
Banghua Zhu, Ziao Wang, Nadim Ghaddar +2
We consider the problem of computing a function of variables using noisy queries, where each query is incorrect with some fixed and known probability . Specifica…
On the Optimal Bounds for Noisy Computing
Banghua Zhu, Ziao Wang, Nadim Ghaddar +2
We revisit the problem of computing with noisy information considered in Feige et al. 1994, which includes computing the OR function from noisy queries, and computing the MAX, SEAR…
A Lego-Brick Approach to Coding for Network Communication
Nadim Ghaddar, Shouvik Ganguly, Lele Wang +1
Coding schemes for several problems in network information theory are constructed starting from point-to-point channel codes that are designed for symmetric channels. Given that th…
Noisy Sorting Capacity
Ziao Wang, Nadim Ghaddar, Banghua Zhu +1
Sorting is the task of ordering elements using pairwise comparisons. It is well known that comparisons are both necessary and sufficient when the outcomes of the…
