论文摘要
我们分析了前向链接之间的相关性对反向散射通信系统能力的影响。为此，我们在相关的瑞利产品褪色通道下获得平均容量的分析表达，以及高和低信噪比（SNR）方案的封闭形式的渐近表达式。我们的结果表明，相关确实对固定目标SNR有害。与共同的信念相反，我们还看到，在考虑固定功率预算的某些情况下，相关性实际上可能是有益的。
We analyse the effect of correlation between the forward and backward links on the capacity of backscatter communication systems. To that aim, we obtain an analytical expression for the average capacity under a correlated Rayleigh product fading channel, as well as closed-form asymptotic expressions for the high and low signal-to-noise ratio (SNR) regimes. Our results show that correlation is indeed detrimental for a fixed target SNR; contrarily to the common belief, we also see that correlation can be actually beneficial in some instances when a fixed power budget is considered.
