This paper presents a method to achieve perception functionality through signal waveform design within a communication system. By leveraging the transmit and receive signal mechanisms based on OFDM (Orthogonal Frequency Division Multiplexing) technology, the method enables the sensing of the dynamic environment in which the communication system operates. The proposed approach involves designing waveform using independent multicarrier channels in existing wireless communication systems. By analyzing the pilot change rate of the received communication signals, this method allows for the perception of both individuals and the environment at the receiving end. Furthermore, the design of parameters such as content, mode, and related processing time intervals of OFDM signals in the communication system accurately facilitates the perception of the dynamic environment, thereby enhancing the stability of the sensing capability.
