Abstract: In this paper, a joint permutation index and code index modulations differential chaos shift keying-based ambient backscatter communication (JPCIM-DCSK-AmBC) is proposed to improve the system performance and data rate. The JPCIM-DCSK-AmBC signal in the proposed system is transmitted using a backscatter device, with multiple bits encoded in a radio frequency (RF) source symbol via joint permutation index and a modulation technique based on code indexing. The information bits are split into two blocks of m p and m c bits, where m p bits are utilized for permutation index and m c bits are utilized for code index bits. The analytic bit error rate (BER) of the JPCIM-DCSK-AmBC over a flat fading channel is derived and verified with the simulation results. The experimental results demonstrate that the suggested system has lower error rate and higher throughput than conventional methods.
