Massive Multiple Access for 6G

2022
This chapter addresses the connectivity problem between a massive number of intermittently active devices contending for transmission of short uplink packets to a single base station. Such a context, usually referred to as 'massive multiple access', deviates sharply from traditional multiple access due to the extremely large device population size ...

Preventing massive automated access to web resources

Computers & Security, 2009
Automated web tools are used to achieve a wide range of different tasks, some of which are legal activities, whilst others are considered attacks to the security and data integrity of online services. Effective solutions to counter the threat represented by such programs are therefore required.

Massive Access with Channel Reciprocity

2019
In this chapter, we propose a comprehensive fully non-orthogonal communication framework for cellular IoT in TDD mode. Firstly, we design a fully non-orthogonal communication scheme which consists of non-orthogonal channel estimation and non-orthogonal multiple access. Then, we analyze the performance of the proposed fully non-orthogonal communication,
