Abstract: Integrated sensing and communication (ISAC) is a promising technology for the sixth-generation (6G) mobile communication networks. By sharing the spectrum, hardware and software, ISAC solutions can save spectrum, energy and cost for both communication and sensing functions. Communication and sensing have different purposes and characteristics, thus resulting conflicts in the waveform synthesis.

The main challenge for ISAC implementation lies in finding suitable waveforms that can be simultaneously used for information transmission and radar sensing. Another challenge for ISAC is to design high performance and low complexity signal processing algorithms.

In this tutorial, we will give a comprehensive tutorial overview on ISAC waveform design. To this end, we first introduce the performance metric for both sensing and communication, followed by fundamental performance trade-off in ISAC. Next, we present the joint waveform design in detail, which covers waveform optimization in spatial domain, precoding matrix design in spatial domain, and optimal power allocation for OFDM subcarriers. Then we discuss the waveform optimization for a cooperative and coexistence radar and communication system. For Radar centric design, we present FMCW radar based method, MIMO radar based method and spread spectrum based method. For communication centric design, we present OFDM signal combined with phase coding, LFM and OFDMA. Finally, we present the signal processing for ISAC, which consists of three parts: signal processing for cyclic prefixed single carrier, signal processing for standard OFDM signal and signal processing for OTFS signal. We also point out promising directions in 6G communication and sensing.
