The integration of radar and communication system is attracting considerable interest due to spectral scarcity and increasing demand for unified radar and communication applications. Two novel schemes combining channel estimation, radar detection, and information exchange are investigated for unified radar communication systems: channel estimation power splitting (EPS) and information exchange power splitting (CPS). Their achievable rate and tradeoff measure are derived and examined with different parameters. Numerical results show that the optimal time ratio and power ratio for channel estimation, radar detection, and information exchange exist. Also, the CPS scheme has the best performance.
