    • A method in a wireless system, including: receiving, at a wireless device, over first and second networks, from each of plural radios of the first and second networks, respective first and second sets of reference signals received from first radios of the first and second networks, and plural further reference signals received from remaining radios of plural radios of the first and second networks, the first radios of the first and second networks located at a common location; calculating first and second sets of normalized reference signals from ratios for each further reference signal of the first and second sets of reference signals with the first and second reference signals of the first and second sets of reference signals; comparing predictions of signal loss based on the first and second sets of normalized reference signals; and determining an estimate of shadow fading or signal reflectors using the comparison result.

    • The invention relates to a device and to a method for testing a mobile radio device in a multiple antenna system using a frequency-selective static channel model for channel simulation in frequency space. In the method according to the invention, the useful data to be transmitted are first allocated to a plurality of carrier frequencies and the associated coding parameters per antenna. The useful data are then modulated onto the carrier frequencies according to the allocation. One or more modulated carrier signals are now distorted in frequency space according to a frequency-selective static channel model. A transmission signal composed of the channel-modeled modulated carrier signals is subsequently transmitted in the period of time to a mobile radio device to be tested.
    • 本发明涉及一种用于使用频率选择性静态信道模型在频域中进行信道仿真的多天线系统中的移动无线电设备的测试方法。 在根据本发明的方法中,首先将要发送的有用数据分配给多个载波频率和每个天线的相关编码参数。 然后根据分配将有用的数据调制到载波频率上。 根据频率选择性静态信道模型,一个或多个调制载波信号现在在频率空间中失真。 由频道建模的调制载波信号组成的传输信号随后在一段时间内传送到待测试的移动无线电设备。
