Second-Order Asymptotics of Hoeffding-Like Hypothesis Tests
K. V. Harsha, Jithin Ravi, Tobias Koch
We consider a binary statistical hypothesis testing problem, where independent and identically distributed random variables are either distributed according to the null h…
Scaling Laws for Gaussian Random Many-Access Channels
Jithin Ravi, Tobias Koch
This paper considers a Gaussian multiple-access channel with random user activity where the total number of users and the average number of active users may grow wit…
Capacity per Unit-Energy of Gaussian Random Many-Access Channels
Jithin Ravi, Tobias Koch
We consider a Gaussian multiple-access channel with random user activity where the total number of users and the average number of active users may be unbounded. For…
Capacity per Unit-Energy of Gaussian Many-Access Channels
Jithin Ravi, Tobias Koch
We consider a Gaussian multiple-access channel where the number of transmitters grows with the blocklength . For this setup, the maximum number of bits that can be transmitted r…
Saddlepoint Approximations for Short-Packet Wireless Communications
Alejandro Lancho, Jöhan Ostman, Giuseppe Durisi +2
In recent years, the derivation of nonasymptotic converse and achievability bounds on the maximum coding rate as a function of the error probability and blocklength has gained atte…
Robust Signaling for Bursty Interference
Grace Villacrés, Tobias Koch, Aydin Sezgin +1
This paper studies a bursty interference channel, where the presence/absence of interference is modeled by a block-i.i.d.\ Bernoulli process that stays constant for a duration of $…
