Abstract
This study investigates a Radar-Communication (RadCom) system based on the orthogonal chirp-division multiplexing (OCDM) scheme, which is introduced as an alternative to its counterpart based on orthogonal frequency-division multiplexing (OFDM). In this context, a description of the system model addressing both communication data obtaining and radar image generation features is presented. Next, both the communication and radar aspects of the introduced OCDM RadCom system are compared with the ones of its OFDM counterpart. It is concluded that the introduced system yields lower bit error rate values, while demanding higher computational complexity and presenting higher sidelobe level than OFDM RadCom.
