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.
