This article proposes a dual-function of radar and communication (DFRC) OFDM waveform design method. This method utilizes the PSK method to modulate communication information on subcarrier complex weight, and consider adjust the location of phase of complex weight. It constructs a quadratic optimization problem with non-convex constraints based on minimizing the weighted integrated sidelobe level joint transmission and reception. The constraints include constant modulus constraints, signal-to-noise ratio loss, BER, and the mainlobe level of the cross-correlation between transmission and reception. Subsequently, the convergence and algorithm effectiveness of W-ADMM algorithm were demonstrated. The final exam results show that the designed waveform can effectively supress sidelobes and ensure communication error rate.
