Development of OCDM system to the organization of information exchange in uav group

A variant of information interaction within the UAV group based on basis of a fully-connected radio network is proposed. During a fixed time interval, each participant in accordance with the s cyclogram has time to exchange information with other participants, implement the principle of ”each to each.” With this approach, in the course of a certain slot a parallel exchange is carried out in pairs, the number of which may be significant. When organizing the exchange in pairs in the full duplex mode, which is justified in case limited number of participants, with the increasing of participants, the requested frequency resource may be unacceptably large. The paper proposes a combined variant of frequency-code division, in which all pairs will communicate in the frequency full duplex mode in one frequency band with code division. At the core of the code division is a multi-channel communication system with m-ary transmission. The noise immunity of the system under different number of participants in the group and various parameters of Gold's pseudo-random sequences used for separation is investigated.
