Soft decision decoding (SDD) provides a better coding gain by making use of the unquantized channel output. In this paper we introduce the concept of a Reliability Level List (RLL); based on the RLL a new SDD algorithm for Binary Phase Shift Keying (BPSK)... see more

A computational experiment is conducted on the possibility of using McElice crypto-code constructions with elliptic codes based on the UMAC algorithm to ensure the implementation of the basic rules of blockchain technology for the transfer of confidential... see more

In this work, construction methods for formally self-dual codes are generalized in the form of block lambda-circulant matrices. The constructions are applied over the rings F_2,R1 = F_2 + uF_2 and S = F_2[u]=(u^3-1). Using n-block lambda-circulant matrice... see more

Active distributed storages need to assure both consistency and dynamic data support, in addition to availability, confidentiality and resiliency. Further, since storage durability suffers in untrusted and unreliable environments, it becomes crucial to (a... see more

In this paper, we study bounds on the number of check digits of linear codes that can detect multiple sub-blocks each affected by e or less random errors and can locate such corrupted multiple sub-blocks. Further, we obtain an upper bound on the number of... see more

We analyse the Space-time Block coding for wireless communication and present an overview of applying MIMO concept and shows how it improves the SNR without decreasing data rates. It provides a new paradigm for transmission over Raleigh fading channel usi... see more

Introduction: The transparent evaluation of projects proposals for scientific research with financial support through calls made by governmental institutions or private organizations becomes extremely important, along with increasing confidence in the res... see more

In this work, a novel architecture for detection of Hybrid MIMO Systems over Rayleigh fading channels is presented. The Hybrid MIMO scheme consists of one Alamouti space-time block code unit, plus  antennas operating as layers of V-BLAST in the trans... see more

Coding Theory is a mathematical domain with many applications in Information theory. Various type of codes and their connections with other mathematical objects have been intensively studied. One of these applications, namely connections between binary bl... see more
