Interference Compensator for Communication Systems with Space-Time Coding

The known methods of signal processing of information transmission systems with space-time coding are quite successful in combating signal fading. However, these methods do not reduce the influence of external interference signals correlated in different reception channels. The article proposes a method for compensating external interference to systems with space diversity. The structure of the interference compensator is described. The method has been experimentally investigated. The experiments used a communication system with 2x space diversity. The proposed interference compensator showed the ability to suppress external narrow-band radio interference by at least 40 dB, and broadband barriers by 15 dB.
