On the transmission performance of DS-CDMA-based drone swarm.

In drone swarm communication, multi-user interference can occur in the transmission within the drone swarm due to the randomness of the drone positions. This article mainly investigates the transmission performance of drone swarm communication, including outage probability and ergodic capacity, using direct sequence code division multiple access (DS-CDMA). In this work, the randomness of the drone position distribution is modeled using random geometry theory. Specifically, the author uses wireless communication modeling and stochastic geometry theories to establish a signal model using DS-CDMA technology. Next, closed-form analytical expressions for outage probability and asymptotic analysis are derived. Based on this, the influence of system factors such as DS-CDMA parameters and transmission distance on the transmission performance is summarized, and numerical results are provided to investigate the effect of the randomness of drone position distribution on the transmission performance between target communication nodes. In addition, the comparison between theoretical numerical results and Monte Carlo simulation results also verifies the correctness of the transmission performance analysis model proposed in this paper.
