摘要

本文描述了实验装置，并介绍了正在巴西进行的中波传播测量活动的初步结果。该试验是巴西政府正在进行的一系列实地试验的一部分，这些试验旨在评估该国DRM标准的性能，其中包括在圣保罗、里约热内卢和贝洛奥里藏特等城市开展的MW、HF和VHF频段的运动。由模拟调幅信号和数字DRM信号组成的混合信号，具有相同的内容，在白天和夜间播出。这里提供的结果包括在圣保罗进行的测量的白天和夜间统计数据。

Medium wave DRM trials in Brazil — Initial results

This paper describes the experimental setup and presents initial results of medium wave propagation measurements campaigns that are being carried out in Brazil. The experiment is part of a series of field trials that are being conducted by the Brazilian Government to evaluate the performance of DRM standard in this country, which includes campaigns at MW, HF and VHF frequency bands in the cities of São Paulo, Rio de Janeiro and Belo Horizonte. A hybrid signal, composed of an analog AM signal and a digital DRM signal, with the same content, were broadcasted in diurnal and nocturnal transmissions. The results presented here include daytime and nighttime statistics of the measurements performed in São Paulo.
