Abstract

Calpa Juajinoy, José Luis; Sampaio Neto, Raimundo (Advisor); Cal-Braz, João Alfredo (Co-advisor). Decoupled signal detection in the up-link of MU-MIMO systems with spatial modulation. Rio de Janeiro, 2017. 71p. This work dissertation presents the results obtained from the conjunction of two proposal techniques for the use in modern systems of communications: the Spatial Modulation and the Decoupling Signal Detection. In the first part are discussed the theorical bases of the signal detection with Spatial Modulation, a comparison between the traditional MIMO systems and the SM-MIMO systems, a bibliographical review about previous works in the topic and the different kinds of detectors that can be used in systems with Spatial Modulation. Then the different techniques of signal decoupling are discussed, which allow the separation in the radio base station of the signals coming from the different classes of users, to simplify and adapt the process of detection and the requirements of the user in the network. Finally a performance analysis in terms of the bit error rate and computational complexity in terms of average number of flops required fot the vector of symbols detected, is done for the studied detectors in the dissertation, using the same different techniques of decoupling studied in this work.

Receivers for the up-link of multiuser MIMO systems with Spatial Modulation

“…Numeric results that consider another scenarios and include propagation and correlation effects between the antennas in the channel matrix were not included in this article due to space limitations. They can be found in [8].…”

“…Durante os últimos anos a tecnologia MIMO tem sido muito importante nas comunicações sem o, já que permite o aumento da taxa de transferŸncia da informação e a redução da taxa de erro. Isto é conseguido com a utilização de diferentes canais na transmissão de dados ou a multiplexação espacial, efeito gerado pelo espaçamento físico das antenas [29]. MIMO é uma parte importante da maioria dos modernos padrões de comunicação sem o.…”
