Integrated sensing and communication (ISAC) has the advantages of efficient spectrum utilization and low hardware cost. It is promising to be implemented in the fifth-generationadvanced (5G-A) and sixth-generation (6G) mobile communication systems, having the potential to be applied in intelligent applications requiring both communication and high-accurate sensing capabilities. As the fundamental technology of ISAC, ISAC signal directly impacts the performance of sensing and communication. This article systematically reviews the literature on ISAC signals from the perspective of mobile communication systems, including ISAC signal design, ISAC signal processing algorithms and ISAC signal optimization. We first review the ISAC signal design based on 5G, 5G-A and 6G mobile communication systems. Then, radar signal processing methods are reviewed for ISAC signals, mainly including the channel information matrix method, spectrum lines estimator method and super resolution method. In terms of signal optimization, we summarize peak-to-average power ratio (PAPR) optimization, interference management, and adaptive signal optimization for ISAC signals. This article may provide the guidelines for the research of ISAC signals in 5G-A and 6G mobile communication systems.

“…According to formula (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14), it can be seen that the frequency of the Chirp signal can change with time and the transformation of K. The linear frequency modulation process is the process of matching the Up chirp signal or Down chirp signal with the baseband signal. When the baseband signal chip data is' 0 ', the Down chirp signal is selected, and when the data is' 1', the Up chirp signal is selected.…”

To address the issue of interference caused by power line channel noise on time transmission signals, a power line time transmission technology based on OFDM modulation is proposed to use linear frequency modulation (LFM) and direct sequence spread spectrum (DS) techniques for its subcarriers. The simulation results show that the power line time transfer technology using LFM-OFDM and DS-OFDM modulation can effectively reduce the bit error rate of the received signal. At the same time, compared to DS-OFDM modulation technology, the power line time transfer technology using LFMOFDM modulation has a lower bit error rate of the received signal.

Abstract.A new DOA estimation method with high resolution is proposed in this paper for vehicular radar and communication integration system in V2V scenario. This method uses digital beam forming algorithm to estimate the weight vector, from which the DOA of other vehicles can be estimated. Firstly, we presents a new digital beam forming algorithm. Secondly, we can estimate the weight vector based on the new algorithm, and then form the direction map. Finally, the DOA can be obtained by determining the maximum value of the direction map. Through simulation and analysis, the proposed method can obtain higher resolution.
