1. MEASUREMENT AND ANALYZE OF UWB INDOOR CHANNEL TEMPORAL DISPERSION IN SEVERAL ENVIRONMENT TYPES / MEDIDAS E ANÁLISE DA DISPERSÃO TEMPORAL DO CANAL DE PROPAGAÇÃO UWB INDOOR EM VÁRIOS TIPOS DE AMBIENTES
This work presents an analysis of the ultra wideband (UWB) channel temporal dispersion characteristics evaluated from the frequency sounding technique over a bandwidth of 850MHz at seven different indoor environment. In each environment, the channel temporal dispersions parameters were assessed in terms of mean delay, delay spread and coherence bandwidth. An

2. MIMO MEASURED CHANNELS: CAPACITY RESULTS AND ANALYSIS OF CHANNEL PARAMETERS / MEDIDAS DO CANAL MIMO INDOOR: ANÁLISE DA CAPACIDADE E DOS PARÂMETROS DO CANAL
Multiple antenna systems known as MIMO (Multiple Input Multiple Output) systems have been proposed as an effective way to address the user demand for high data rate applications in wireless systems. This is especially important in systems where the capacity attained with traditional techniques is very limited due to the adverse characteristics of the propaga
