On Communication for Distributed Babai Point Computation

Maiara F. Bollauf et al.

Summary: The study introduces a communication-efficient distributed protocol for computing the approximate nearest point in a lattice for a random vector, and examines the error probability under different probability models. The research reveals that the error probability may tend towards unity with increasing dimensions, providing insights for lattice-based algorithms.

Precoder Design for Communication-Efficient Distributed MIMO Receivers With Controlled Peak-Average Power Ratio

Vinay A. Vaishampayan

Summary: This paper explores the communication over a relay-assisted MIMO channel, proposing that using a rational-forcing precoder can reduce symbol error probability. A tradeoff between peak to average power ratio in the transmitter and the rate of communication between relays and the central decoder is identified in the design of the precoder.

Globally Optimal Design of a Distributed Scalar Quantizer for Linear Classification

Sorina Dumitrescu et al.

Summary: This work focuses on designing a distributed scalar quantizer for linear classification with two encoders, aiming to minimize the classification error. By proving the equivalence of the optimal DSQ design problem to a minimum weight path problem on a weighted directed acyclic graph and proposing a solution algorithm with specific time complexity, the considerable superiority of the proposed approaches is demonstrated in experimental results.
