Query: Robust OFDM integrated radar and communications waveform design based on
  information theory   An integrated radar and communications system (IRCS) where a monostatic radar
transceiver is employed for target classification while simultaneously used as
a communications transmitter is considered. The radar combined
propagation-target response (joint response of the radar propagation channel
and target) and communications channel response are generally frequency
selective but the corresponding frequency response functions are not exactly
known. In particular, these frequency response functions are only known to lie
in an uncertainty class. To ensure the IRCS simultaneously provides acceptable
target classification performance and communications rate, a robust orthogonal
frequency division multiplexing (OFDM) integrated radar and communications
waveform (IRCW) design method is proposed. The approach finds a waveform that
simultaneously provides a sufficiently large weighted sum of the communications
data information rate (DIR) and the conditional mutual information (MI) between
the observed signal and the radar target over the entire uncertainty class.
First, the conditional MI and DIR based on the integrated OFDM radar and
communications waveform are derived. Then, a robust OFDM IRCW optimization
problem based on the minimax design philosophy is developed such that
closed-form solution is derived. Finally, several numerical results are
presented to demonstrate the effectiveness of the proposed method.
