A method for space-time signal processing in systems with frequency hopping and an apparatus for implementation thereof relates to electric communications technique and can be used in information transmission systems with operating frequency hopping. In the space-time signal processing method in communication systems with frequency hopping at transmitting and receiving sides a set of coefficients is used. Basing on said coefficients frequency hopping is formed via changing a ratio signal/interference by control receivers at receiving parts over all allocated frequencies for communication session, frequency position with the best signal/interference ratio is chosen, a signal of this frequency is transmitted, in receivers the signal processing is performed using two channels of the weight-coefficient vector adjustment, remeasurement and readjustment to transmitter another frequency is performed, if ratio of signal/interference decreases at receiving input, or current frequency is maintained with the constant signal/interference ratio. To gain this, a synchronizer, a counter and key switches are incorporated in the apparatus.. Using the proposed invention the increase of noise immunity is obtained; time of system adaptation to current SPO during transmission of an information packet is reduced, synchronous operation of a processor of weight-coefficient vector adjustment while frequency turning is provided. |
