A Probably Approximately Correct Analysis of Group Testing Algorithms
Sameera Bharadwaja H., Chandra R. Murthy
We consider the problem of identifying the defectives from a population of items via a non-adaptive group testing framework with a random pooling-matrix design. We analyze the suff…
Half-Duplex APs with Dynamic TDD vs. Full-Duplex APs in Cell-Free Systems
Anubhab Chowdhury, Chandra R. Murthy
In this paper, we present a comparative study of half-duplex (HD) access points (APs) with dynamic time-division duplex (DTDD) and full-duplex (FD) APs in cell-free (CF) systems. A…
