N2 - Due to limitations in the bandwidth resources, sharing the spectrum across several modalities has become increasingly important. In this paper, we will consider OFDM spectral sharing between radar and wireless communication systems. We will define and compute the importance of each sub-carrier to both the modalities by considering the radar detection performance and channel capacity. We will design the OFDM waveforms for communications and radar by appropriately allocating the sub-carriers using these importance functions. Using numerical simulations, we will demonstrate the performance of our proposed design mechanism.
