In order to achieve a more economical spectrum and hardware usage, it is suggested that sensing and communication should be performed using the same radio and frequency band. This invention proposes a scheme that could be used for joint sensing and communication for in-band full duplex radios. The main idea is to utilize superimposed waveforms for sensing and communication, and separate these in the receiver in order to extract the relevant information. Though the transceiver is able to perform sensing, transmission and reception simultaneously, it is suggested that the it should be able to adapt, and perform any combination of these operations in order to maintain operational under varying conditions. In this study, additional degree of freedom regarding coexistence of different waveforms which are optimized for both application separately is introduced from the full-duplex systems point of view.
