Dual-Functional Radar and Communication System Based on Hybrid Index Modulation
Abstract
This letter proposes a dual functional radar and communication scheme utilizing a phased array radar and hybrid index modulation to achieve higher communication data rate. In this proposed scheme, information bits are conveyed through hybrid index modulation including frequency index modulation and spatial index modulation with higher degree of freedom. In addition, a spatial codebook adjustment is introduced to further increase the system performance. Theoretical analysis and simulation results demonstrate that the proposed scheme achieves a higher data rate under the given hardware requirements, with a tolerable impact on radar performance.
