Fault tolerant adaptive filter structure based on the generalized subband decomposition of FIR filters

This paper investigates the use of the generalized structural subband implementation of adaptive FIR filters in high-speed fault tolerant adaptive filtering. The convergence behavior of the proposed fault tolerant adaptive structure, after a coefficient fault has occurred, is analyzed. The problems of identifying the occurrence of a fault and the faulty coefficient are examined. The convergence behavior of the proposed subband structure during a fault occurrence is compared to the behavior of previously reported structures.<<ETX>>
