Abstract

We consider the design of spectrum sharing communication waveforms that may partially overlap spectrally with a pulse-Doppler radar yet maintain a low, predictable level of interference with radar operation. This is in contrast to traditional communication waveforms, which can interfere with radar operation despite having a negative interference-to-noise ratio. A new communication symbol design is derived as an improvement on previously developed subspace projection based designs. The new design provides a significant reduction in interference to radar operation while maintaining comparable symbol error rate performance to the previous methods.
雷达频谱共享环境下相邻/重叠通信波形设计的影响
我们考虑了频谱共享通信波形的设计,这些波形可能与脉冲多普勒雷达在频谱上部分重叠,但对雷达操作保持低的、可预测的干扰水平。这与传统的通信波形相反,传统的通信波形尽管具有负干扰噪声比,但仍可能干扰雷达操作。在子空间投影设计的基础上,提出了一种新的通信符号设计。新设计显著减少了对雷达操作的干扰,同时保持了与以前方法相当的符号错误率性能。
