Pilot Design for BEM-Based Channel Estimation in Doubly Selective Channel
IEEE Transactions on Vehicular Technology, 2020 This paper investigates pilot design for enhanced channel estimation in single carrier communication systems over doubly-selective channels (DSC). Our contribution is twofold: first, we propose to use Huffman sequences as pilot clusters with low peak-to ...

A Bayesian approach to pilot-pivotal trials for bioequivalence assessment
BMC Medical Research Methodology, 2023 Background To demonstrate bioequivalence between two drug formulations, a pilot trial is often conducted prior to a pivotal trial to assess feasibility and gain preliminary information about the treatment effect. Due to the limited sample size, it is not
