Abstract:
1. A method for providing a redundant or distinct transmission feature to a communication system, comprising: detecting at the communication system if there is a communication systems fault resulting from an operational failure occurring in equipment thereof which prevents a beam produced by an antenna array of said communication system from being properly formed or pointed; if the communication systems fault is not detected, generating by a transmit system of said communication system a plurality of modified transmit signals by combining a transmit signal with a plurality of complex weights and transmitting the plurality of modified transmit signals from a plurality of antenna elements of said antenna array of the transmit system to an object of interest; and if the communication systems fault is detected, generating by said transmit system a plurality of redundant or distinct transmit signals by combining the transmit signal with a plurality of first orthogonal or approximately orthogonal numerical sequences and synchronously transmitting the plurality of redundant or distinct transmit signals from the plurality of antenna elements.
