Resumo: | The aim of this dissertation is to present three new proposals for resource allocation for OFDMA systems, doing an analysis of their performances, comparing them with two other subcarriers and bits allocation schemes. The five algorithm presented, the first algorithm is the Water-filling Algorithm and its maximizes the throughput of OFDM symbol. The second algorithm is the Two-Steps Algorithm. The main advantage of this algorithm is the fact that the minimal data rate required for each user is respected, which means that the individual QoS is achieved. The algorithms proposed are based on the modifications of the Water-filling Algorithm, defined as Modified Water-filling Algorithm - Maximization of the Throughput, the Modified Water-filling Algorithm - Robustness and the Modified Water-filling Algorithm - Maximization of the Robustness. Those algorithms utilize the frequency response of the communication channels and the minimal throughput of each user to allocate the resources of the systems. Their performances are analyzed in different communication channels, where the results of the distribution of the resources are more equality among the users comparing it with the obtained by the Water-filling algorithm and has a higher average throughput when compared with the Two-steps algorithm. |

Disserta????o( Programa 1) - Instituto Nacional de Telecomunicacoes, [Santa Rita do Sapuca?] .http://tede.inatel.br:8080/tede/handle/tede/39The aim of this dissertation is to present three new proposals for resource allocation for OFDMA systems, doing an analysis of their performances, comparing them with two other subcarriers and bits allocation schemes.

Dos cinco algoritmos apresentados, o primeiro ? o algoritmo de Water-filling. Este algoritmo maximiza a vaz?o do s?mbolo OFDM pela an?lise da resposta em frequ?ncia do canal. O segundo ? o algoritmo Two-Steps. Sua principal vantagem ?e garantir as vaz?es m?nimas de cada usu?rio, o que faz com que as QoS individuais sejam atingidas. Os algoritmos propostos s?o baseados em modifica??es do algoritmo de Waterfilling, definidos como Algoritmo de Water-filling Modificado - Maximiza??o da Vaz?o, o Algoritmo de Water-filling Modificado - Robustez e o Algoritmo de Water-filling Modificado - Maximiza??o da Robustez. Estes algoritmos utilizam a resposta em frequ?ncia dos canais de comunica??o e as vaz?es m?nimas de cada usu?rio para realizar a aloca??o dos recursos ao sistema. Seus desempenhos s?o analisados em diferentes canais de comunica??o, onde os resultados mostram a exist?ncia de uma maior igualdade de distribui??o de recursos entre os usu?rios se comparado com a distribui??o obtida pelo algoritmo de Water-filling e apresenta uma maior vaz?o m?dia quando comparado com o algoritmo Two-steps.Submitted by Tede Dspace (tede@inatel.br) on 2016-07-08T17:10:05Z No. of bitstreams: 2 license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5) Disserta??o V.Final Anderson Daniel Soares.pdf: 4136951 bytes, checksum: 89c4b9206fda3de959ecf78a49c9400a (MD5)Made available in DSpace on 2016-07-08T17:10:05Z (GMT).
