Abstract

This paper analysis the performances of a single antenna handheld receiver in detecting a signal in a Rayleigh multipath fading environment. If the antenna is spatially fixed during the time interval that the signal is sampled then signal coherency is maintained. However, the signal will be subject to statistically large fading losses. The alternative is to spatially translate the antenna along some arbitrary random trajectory during the snapshot interval. It will be shown that a significant net processing gain resulting from randomly moving the antenna relative to keeping it stationary is achievable. It is further demonstrated that for a given utilization scenario, there is an optimum trajectory size which maximizes the processing gain advantage of the moving antenna. An extensive set of measurements based on CDMA-2000 pilot signals propagated from outdoor terrestrial base stations, captured in indoor multipath environments using stationary and moving antennas are used to experimentally verify these theoretical findings.

合成天线阵列在室内环境下的信号检测性能

本文分析了单天线手持接收机在瑞利多径衰落环境下检测信号的性能。如果天线在采样信号的时间间隔内空间固定，则保持信号的相干性。然而，信号将受到统计上较大的衰落损失。另一种方法是在快照间隔内沿任意随机轨迹对天线进行空间平移。将显示，相对于保持天线静止，随机移动天线产生的显著净处理增益是可以实现的。进一步证明，对于给定的利用场景，存在一个最优轨迹尺寸，使移动天线的处理增益优势最大化。一组基于室外地面基站传播的CDMA-2000导频信号的广泛测量，使用固定和移动天线在室内多径环境中捕获，用于实验验证这些理论发现。
