In order to meet the requirements of anti-jamming communication, a direct sequence spread spectrum (DSSS) communication receiver based on Rydberg atom technology is first proposed and experimentally verified. By constructing a Rydberg atomic four-level system, real-time optical readout of amplitude modulated spread spectrum signals is achieved using Electromagnetically Induced Transparency (EIT) spectroscopy. The relationships between EIT transmission, electric field strength, and Rabi frequency of coupling laser are theoretically analyzed, and communication receptions are conducted on four groups of signals with spreading factors of 10, 20, 50, and 100 in the experiments. The experiments show that the digital communication at rates of up to 100 kbps can be reliably achieved by the designed Rydberg atom antenna, with a bit error rate of 0 for the original signals. In addition, the power spectral densities are decreased respectively to 1/10, 1/20, 1/50, and 1/100 under four different spreading factors, which verifies the feasibility and effectiveness of the Rydberg atomic receiver for DSSS signals. At the same time, the advantages of frequency selectivity and anti-electromagnetic interference are possessed by the Rydberg atom, providing the possibility for its application in navigation and military communication.
