论文摘要
本文考虑了一个底部脉冲雷达 - 细胞光谱共享方案，其中蜂窝系统使用试验辅助解调，统计通道状态信息（S-CSI）估计和有限的反馈方案。在现实的系统模型下，上限和下限是在有限的CSI估计窗口中至少通过雷达脉冲序列干扰指定数量的飞行员信号的概率。对于重要的特殊情况，还会得出确切的概率，这些概率揭示了实现下限的操作制度。使用这些结果，本文（a）提供了有关飞行员干扰最小化方案的见解，以进行准确的相干符号解调，并且（b）证明了试验辅助方法无法准确估算脉冲雷达干扰通道的S-CSI，以提供广泛的雷达重复间隔。
This paper considers an underlay pulsed radar-cellular spectrum sharing scenario, where the cellular system uses pilot-aided demodulation, statistical channel state information (S-CSI) estimation and limited feedback schemes. Under a realistic system model, upper and lower bounds are derived on the probability that at least a specified number of pilot signals are interfered by a radar pulse train in a finite CSI estimation window. Exact probabilities are also derived for important special cases which reveal operational regimes where the lower bound is achieved. Using these results, this paper (a) provides insights on pilot interference-minimizing schemes for accurate coherent symbol demodulation, and (b) demonstrates that pilot-aided methods fail to accurately estimate S-CSI of the pulsed radar interference channel for a wide range of radar repetition intervals.
