  • Patent number: 8723728
    Abstract: A failure compensation method includes detecting a Digital Beam-forming (DBF) coefficient of each of multiple transceiver channels in real time. When a failure of any one of the transceiver channels is detected, a current group of DBF coefficients of the multiple transceiver channels at a current failure status and corresponding failure mode information are obtained. Optimization processing is performed on the current group of DBF coefficients through a preset optimization algorithm so as to calculate a first group of DBF coefficients which is more adaptive to the failure mode information than the current group of DBF coefficients. The DBF coefficients of the transceiver channels are updated according to the first group of DBF coefficients.
