UWB-TR接收机性能分析

Performance analysis of UWB-TR receiver

在确定STR接收机模型的基础上,采用对接收机输出噪声进行高斯近似的方式对UWB-STR接收机性能进行了分析,得到UWB-STR接收机的误码性能表达式。表明该种接收机误码性能不仅与信噪比有关,而且与噪声输入带宽和积分时间有关,其特性可类推到其他类型的自相关接收机。最后与其他现有文献的结论进行了对比及修正,并提供了UWB-ATR的误码性能表达式。

Based on the determination of UWB-STR receiver model, the performance of UWB-STR receiver was analyzed by using a Gaussian approximation of the noise components at the output of the receiver and the analytical expressions of bit error rate（BER） performance were derived. The result shows that the receiver performance of BER is relevant to not only signal-to-noise ratio, but also input noise bandwidth and integration time. The characteristics can be applied to other kind of autocorrelation receivers. Finally, the analytical expressions of BER were compared with that in existing literatures and some results were modified. In addition, the expressions of BER for UWB-ATR receiver were given.
