As Infostations atendem a uma demanda por serviços multimídia com alta qualidade e alta taxa de dados. O desafio para o projeto do sistema Infostation é como baixar o máximo de bits de informação quando um usuário móvel passa por uma célula Infostation. Uma arquitetura de rádio TDMA/TDD de taxa variável é escolhida para estudo e implementação experimental devido à sua flexibilidade em um ambiente multiusuário. Um esquema de transmissão adaptativa controlada por código convolucional perfurado compatível com taxa de símbolos e taxa é proposto para o projeto de rádio Infostation. A taxa de transferência de dados é analisada para um usuário móvel que passa por uma célula do Infostation. A análise indica que três taxas de dados de 0.25, 1.0 e 2.0 Mbps alcançam mais de 85% do rendimento teórico, ao mesmo tempo que simplificam a implementação. O código convolucional perfurado é estudado para maximizar o rendimento do Infostation. É feita uma recomendação para usar o esquema de codificação de taxa 1/2. Um algoritmo eficiente de adaptação de taxa é proposto e pode rastrear bem o canal de desvanecimento Rayleigh e a perda de capacidade é insignificante em várias condições.

Abstract: Infostations serve a demand for multimedia services with high quality and high data rate. The challenge for Infostation system design is how to download as many information bits when a mobile user drives through an Infostation cell. A variable rate TDMA/TDD radio architecture is chosen for study and experimental implementation because of its flexibility in a multi-user environment. A symbol rate and rate compatible punctured convolutional code controlled adaptive transmission scheme is proposed for the Infostation radio design. Data throughput is analyzed for a mobile user passing through an Infostation cell. The analysis indicates that three data rates at 0.25, 1.0 and 2.0 Mbps achieve greater than 85% of the theoretical throughput while simplifying the implementation. The punctured convolutional code is studied to maximize the Infostation throughput. A recommendation is made to use rate 1/2 coding scheme. An efficient rate adaptation algorithm is proposed and it can track the Rayleigh fading channel well and the capacity loss is negligible in various conditions.
