Abstract:

In this report, we discuss the bistatic MIMO DFRC system waveform design method. Particularly, Particularly, we minimize the maximal ratio of the error distances from desired symbols to the distances from undesired symbols, referred to as “discriminant” distances, to enhance the separability of received symbols, which in turn improves the SER. While we derive two CRLB constraints on DOD and DOA separately as the semi-definite programming formulations to avoid complex computation from fractional constraints via constructing two special positive semi-definite matrices. Moreover, the aforementioned “distance-similarity”-based metric is extended to the “direction-similarity”-based metric. Numerical results demonstrate the effectiveness of our proposed communication metrics and design solutions in terms of SER performance and robustness against non-linear phasenoise compared with the competing methods.
