  Abstract: Sharing spectrum with incumbents such as radar systems is an attractive solution for cellular operators in order to meet the ever-growing bandwidth requirements and ease the spectrum crunch problem. In order to realize efficient spectrum sharing, interference mitigation techniques are required. In this letter, we address techniques to mitigate multiple-input–multiple-output (MIMO) radar interference at MIMO cellular base stations (BSs). We specifically look at the amount of power received at BSs when radar uses null space projection (NSP)-based interference mitigation method. NSP reduces the amount of projected power at targets that are in close vicinity to BSs. We study this issue and show that this can be avoided if radar employs a larger transmit array. In addition, we compute the coherence time of channel between radar and BSs and show that the coherence time of channel is much larger than the pulse repetition interval of radars. Therefore, NSP-based interference mitigation techniques that depend on accurate channel state information (CSI) can be effective as the problem of CSI being outdated does not occur for most practical scenarios.
