  • Abstract
    The optimal design of a Kalman filter is considered in respect of its finite wordlength (FWL) characteristics taking into account the round-off noise due to state quantization. The issues are particularly relevant in the design of FWL Kalman filters for continuous-time systems operating under a fast sampling rate. The optimum filter structure includes state residue feedback compensation which can result in the saving of many bits of additional state wordlength.
