Abstract
Multicarrier Direct Sequence-CDMA (MC-DS-CDMA) is a well known modulation approach, that has desirable properties for joint radar-communications waveform design. We are considering radio frequency sensing and communications systems that are co-designed for mutual benefit. Such Integrated Sensing and Communication (ISAC) systems have a variety of civilian and military applications and will be in the core of emerging 6G wireless systems. A well-designed MC-DS-CDMA joint radar-communication waveform should (1) have Ambiguity Function (AF) close to ideal thumbtack shape, (2) facilitate using LPI/LPD waveforms and (3) allow for efficient interference management among different users and tasks in co-designed ISAC systems. In this paper we propose MC-DS-CDMA waveform designs for ISAC and investigate their properties including AFs, and cross-correlation among the waveforms.Description
