摘要

集成传感与通信(ISAC)技术被认为是未来移动通信系统中潜在的关键技术。为了充分利用频谱资源，移动通信系统不仅可以工作在连续频带，还可以工作在非连续频带。工作在非连续频带的正交频分复用(OFDM)信号被称为非连续OFDM (NC-OFDM)。为了提高基于NC-OFDM的ISAC信号的抗噪声性能，根据通信信令提出了一种改进的信号处理算法。最后，通过仿真验证了该算法的可行性。与传统的信号处理算法相比，该算法在非连续频谱中具有更好的抗噪声性能。

Robust ISAC Signal Processing on Unlicensed Spectrum Bands

The integrated sensing and communication (ISAC) technology is regarded as a potential key technology in the future mobile communication systems. In order to make full use of spectrum resources, mobile communication systems work not only in continuous frequency band but also in non-continuous frequency band. The orthogonal frequency division multiplex (OFDM) signal working in non-continuous frequency band is called non-continuous OFDM (NC-OFDM). In order to enhance the anti-noise performance of ISAC signal based on NC-OFDM, an improved signal processing algorithm is proposed according to the communication signaling. Finally, the feasibility of the proposed algorithm is verified by simulation. Compared with traditional signal processing algorithms, the proposed algorithm has better anti-noise performance in non-continuous spectrum.
