Abstract

In this work, different spreading sequences are presented and investigated with regard to their usability in joint communication and sensing (JCAS) systems. Gold codes, Kasami codes, maximum-length sequences (m-sequences) and Zadoff-Chu sequences are compared with each other in terms of dynamic range (DR), number of sequences in their subset and cross-correlation (CC) properties. Radar measurements were performed to prove the theoretical results. M-sequences and Zadoff-Chu sequences have the best DR. For a sequence length of 1023, the m-sequence achieved a DR of 57.2 dB. The Zadoff-Chu sequence suffers more from hardware non-idealities than m-sequences. The disadvantage of these two sequences is the high CC within their code family, which prohibits the use of this sequence in a network with many different participants. Gold codes and Kasami codes have a better CC but a very limited DR.
