摘要：
To facilitate the increased demand on the radio frequency spectrum, the federal communications commission (FCC) allows spectrum sharing between 4G long term evolution (LTE) communications and radar. A cognitive radar that employs metacognition and many dynamic spectrum access (DSA) techniques to successfully share the spectrum has been developed. This paper suggests metrics to be used to characterize these techniques in terms of mutual interference with the LTE communications. In particular, a Block Collison rate (BCR) metric is proposed to quantitatively analyze the effect of the radar on LTE communications from an outside observer's perspective.
