A fading channel simulator implementation based on GPU computing techniques
Channel simulators are powerful tools that permit performance tests of the individual parts of a wireless communication system. This is relevant when new communication algorithms are tested, because it allows us to determine if they fulfill the communications standard requirements. One of these tests consists of evaluating the system performance when a communication channel is considered. In this sense, it is possible to model the channel as an FIR filter with time-varying random coefficients. If the number of coefficients is increased, then a better approach to real scenarios can be achieved; however, in that case, the computational complexity is increased. In order to address this issue, a design methodology for computing the time-varying coefficients of the fading channel simulators using consumer-designed graphic processing units (GPUs) is proposed. With the use of GPUs and the proposed methodology, it is possible for nonspecialized users in parallel computing to accelerate their simulation developments when compared to conventional software. Implementation results show that the proposed approach allows the easy generation of communication channels while reducing the processing time. Finally, GPU-based implementation takes precedence when compared with the CPU-based implementation, due to the scattered nature of the channel. � 2015 R. Carrasco-Alvarez et al
Contribution to the design of nanodevices and communication protocols for nanonetworks in the THz band
Mención Europeo / Mención Internacional: Concedido[SPA] Esta tesis doctoral se presenta bajo la modalidad de compendio de publicaciones.[ENG] This doctoral dissertation has been presented in the form of thesis by publication. Electromagnetic (EM) nano-communications is a new paradigm encompassing all concerns related to the exchange of information among devices operating in the Terahertz band (0.1-10 THz). A nano-network infrastructure consisting of a high number of nano-devices should be designed to ensure robust, reliable, and coordinated data transmission. This will enable a plethora of forthcoming applications and services in different research fields, such as medicine, environmental science, on-chip communications, or software-defined materials, which will lead to outstanding advances. Nevertheless, EM nano-communications is a recent paradigm that lacks the maturity of other well-established communication fields, so the presented thesis contributes to this maturation process by researching both the hardware and the communication mechanisms upon which THz-based nano-networks could operate. As a Thesis by compilation, the 7 articles published during this Ph.D. program are presented and commented. Each of such articles looks into different key aspects that help closing the gap between theory and practice in THz-based nano-communications. Thus, in the first two chapters of this document, the reader will be introduced to the context and objectives of the thesis. In particular, the second chapter is divided into two subsections: general objectives, which are set into the global background; and specific objectives, grouped by publication. In the next seven chapters, the seven corresponding articles are presented and commented. For each of them, a brief summary, the methodology followed, an overview of the results and contributions, and final conclusions are included. Finally, in the two last chapters, the final conclusions and future lines of this thesis are discussed.Escuela Internacional de Doctorado de la Universidad Politécnica de CartagenaPrograma de Doctorado de Tecnologís de la Información y las ComunicacionesLos artículos que constituyen la tesis son los siguientes: 1.
