  This article introduces adaptations to the conventional frame structure in
binary phase-modulated continuous wave (PMCW) radars with sequence generation
via linear-feedbck shift registers and additional processing steps to enable
joint radar-communication (RadCom) operation. In this context, a preamble
structure based on pseudorandom binary sequences (PRBSs) that is compatible
with existing synchronization algorithms is outlined, and the allocation of
pilot PRBS blocks is discussed. Finally, results from proof-of-concept
measurements are presented to illustrate the effects of the choice of system
and signal parameters and validate the investigated PMCW-based RadCom system
and synchronization strategy.
