Abstract
  This paper reviews the characteristics of the main digest algorithms, and presents a new derivation of the leftover hash lemma, using the collision probability to derive an upper bound on the statistical distance between the key and seed joint probability, and the hash bit sequence distribution. The ...  Read More

Abstract
  This paper presents an investigation on the performance of the Non-Orthogonal Multiple Access (NOMA) in the power domain scheme. A Power Allocation (PA) method is proposed from NOMA throughput expression analysis. This method aims to provide fair opportunities for users to improve their ...  Read More
