Abstract

Many radio applications require a Signal-to-Noise Ratio (SNR) Enhancer to combat the radio channel impairments. In this paper, we are particularly interested in combating the radio channel impairments resulted from long-term and short-term channel variations. The SNR Enhancer pre-conditions the received signal strength (RSS) of the signal such that the SNR of the signal is increased; hence the system performance may be improved. This paper derives the achievable performance of possible approaches, and compares the performance characteristics of the approaches. The results indicate the Maximum RSS approach outperforms the Average RSS approach for the applications intended‥
信噪比增强器
许多无线电应用需要信噪比(SNR)增强器来对抗无线电信道损伤。在本文中,我们特别感兴趣的是对抗由长期和短期信道变化引起的无线电信道损伤。所述信噪比增强器对所述信号的接收信号强度(RSS)进行预处理,从而使所述信号的信噪比增加;因此,可以提高系统的性能。本文推导了各种方法的可实现性能,并比较了各种方法的性能特点。结果表明,对于预期的应用来说,最大RSS方法优于平均RSS方法
