Original Abstract:
This paper develops an efficient index modulation (IM) approach for the jointradar-communication (JRC) system based on a multi-carrier multiple-inputmultiple-output (MIMO) radar. The communication information is embedded intothe transmitted radar pulses by selecting the corresponding indices of thecarrier frequencies and antenna allocations, providing two degrees of freedom.Our contribution involves the development of a novel codebook based minimumEuclidean distance (MED) maximization and a constellation randomizationpre-scaling (CRPS) scheme for efficient IM-JRC transmission. It can be inferredthat the IM approach integrating the CRPS scheme followed by the codebookdesign maximizes the signal-to-noise ratio gain. The numerical results supportthe effectiveness of the proposed approach and show enhanced bit error rateperformance when compared to the existing baseline.
Context On This Paper:
This paper presents a new approach for joint radar-communication (JRC) systems using a multi-carrier multiple-input multiple-output (MIMO) radar. The main objective is to embed communication information into radar pulses using index modulation (IM) with two degrees of freedom. The research question is how to develop an efficient IM approach for JRC systems. The methodology involves a novel codebook based minimum Euclidean distance (MED) maximization and a constellation randomization pre-scaling (CRPS) scheme. The results show that the proposed approach improves the signal-to-noise ratio gain and reduces the bit error rate compared to the existing baseline. The conclusion is that the proposed approach is effective and efficient for JRC systems.
Flycer’s Commentary:
This paper presents an innovative approach to joint radar-communication (JRC) systems using index modulation (IM) and a multi-carrier multiple-input multiple-output (MIMO) radar. The authors propose a novel codebook based minimum Euclidean distance (MED) maximization and a constellation randomization pre-scaling (CRPS) scheme for efficient IM-JRC transmission. The results show that this approach maximizes the signal-to-noise ratio gain and improves bit error rate performance compared to existing methods. This research has implications for small businesses interested in utilizing AI for communication and radar systems, as it provides a more efficient and effective approach to JRC systems. By implementing this approach, small businesses can improve their communication and radar capabilities, leading to better performance and increased competitiveness in their respective industries.
