论文摘要
在这项研究中，提出了一种新型的传输方案，以同时和分配的带宽同时提供雷达感应和通信目标。提出的传输框架非直接外交叠加了两个不同的波形，这些波形是用于雷达感应和正交频施加（OFDM）的频率调制连续波（FMCW），用于通信。此外，还引入了通过雷达传感功能执行通道估计的接收器方案，而不会降低通信操作的数据速率。在数值评估中，即使信噪比（SNR）较低，而拟议的系统也可以达到良好的传感准确性，而与完美通道状态信息（CSI）的假设相比，目标比特率率（BER）的通信性能仅为0.6 dB，而没有任何飞行员的飞行员超过ofdm subdm subcarriers。
In this study, a novel transmission scheme is proposed to serve radar-sensing and communication objectives at the same time and allocated bandwidth. The proposed transmitted frame non-orthogonally superimposes two different waveforms, which are frequency modulated continuous-wave (FMCW) for radar-sensing and orthogonal frequency division multiplexing (OFDM) for communication. Also, the receiver scheme that performs channel estimation via radar-sensing functionality without degrading data rate of communication operation is introduced. As numerically evaluated, the proposed system achieves good sensing accuracy even if the signal-to-noise ratio (SNR) is low, and communication performance is only 0.6 dB less at the target bit-error rate (BER) of 1% compared to the assumption of perfect channel state information (CSI) without any pilot overhead over OFDM subcarriers.
