- W4322730936 abstract "This letter proposes a virtual-array-based waveform optimization scheme for broadband joint radar-communication systems. We first formulate a problem of minimizing Cramér-Rao bound (CRB) of radar subject to communication constraints. To reduce the high complexity of directly solving the problem, we allocate the virtual arrays to users according to their communication thresholds and minimize the largest eigenvalue of the CRB matrix. Then, the optimization problem can be solved by semi-definite programming but the solutions are not always available. We finally propose a low-complexity solution that minimizes the CRB first and then transforms the optimization results to meet the constraints on communications. Simulation results are provided and verify the effectiveness of the proposed scheme." @default.
