Partitioned cyclic code shift keying for JTIDS

In this paper, we propose partitioned cyclic code shift keying (PCCSK) for the Joint Tactical Information Distribution System (JTIDS) by combining a Hadamard matrix and a modified maximal length sequence (MMLS). The proposed approach adaptively increases the transmission data rate within a limited transmission range in the battlefield. By exploiting a new code set as a spreading code and by adopting code selection, the system is easily able to achieve higher spectral efficiency. For additional performance enhancement, we apply adaptive channel coding with PCCSK, and we derive the appropriate code pairs. Monte Carlo simulations are conducted to show the transmission ranges of the proposed scheme, and the results show that PCCSK with adaptive coding can support a higher data rate with a reasonable transmission range.
