Abstract

"MéTODO E EQUIPAMENTO PARA TESTAR UM LINK SEM FIO UTILIZANDO CANAIS DE TRANSPORTE E TAXAS CONFIGURáVEIS POR APLICAçãO DE QUADROS DE VOZ DE MODELAçãO DE CADEIA DE MARKOV DE UM ENCODIFICADOR DE FALA AMR E QUADROS SID". Técnicas para testar um link de comunicação sem fio utilizando canais e taxas configuráveis. Um serviço de teste W-Markov pode ser invocado para testar e/ou verificar o desempenho do downlink/uplink utilizando pelo menos um canal de transporte para cada link. Cada canal de transporte pode ser configurado individualmente. O serviço de teste W-Markov suporta a geração de dados de teste com base em uma seqüência de dados definida ou um gerador de número pseudo-aleatório. O teste pode ser realizado com base em um modelo de atividade pseudo-aleatória ou determinado. Para o teste de chamada de voz, um modelo Markov de primeira ordem pode ser utilizado para modelar a atividade de voz e para selecionar a taxa para uso para cada intervalo de tempo de transmissão (TTI ) . Para as múltiplas taxas adaptativas (AMR), o teste pode ser realizado com base nas taxas AMR configuráveis e nos tipos descritor silencioso (SID) . Os processos de geração de dados de teste são sincronizados entre o transmissor e o receptor. Taxas de erro de bit, quadro e/ou bloco e outras estatísticas podem ser coletadas.
