Application of adaptive control algorithms to improve the performance of a wireless optical communication channel
The possibility of using adaptive control algorithms in wireless optical systems to improve their performance is considered. The use of feedback is proposed to create a dynamic system using the adjustment of the transmitted power level, changing the type of modulation and coding rate for atmospheric attenuation. Modeling and analysis of the system parameters at various distances with a data transmission rate of 1 Gbit / s, taking into account the propagation of an optical signal in free space, have been carried out. The performance of the proposed wireless optical communication system with dynamic control is estimated at quality indicator BER no more than 10-8.
