I. Introduction
Next-generation wireless applications are demanding access to limited spectral resources, and have opened research in the area of combining multiple functions within the same system and frequency band [1]. These may entail radar, communications and/or other applications that can leverage common RF hardware and frequency bands to enhance the capabilities of single devices. The challenge of integrating multiple functions within the same system is that they often have independent pulse and packet schedules that contend for the same hardware and spectral resources, which requires that the underlying waveforms be modified and/or their performance sacrificed.
