Signal restoration using left-sided and right-sided autoregressive parameters

摘要

Signal reconstruction methods reconstruct a missing portion (107) of a signal (X(i)) from a first known portion (107) of the signal preceding the missing portion, and a second known portion (111) of the signal succeeding the missing portion. The first known portion of the signal is represented using a first autoregressive model (217) and the second known portion of the signal is represented using a second autoregressive model (214). These methods construct a signal estimate from the first and second autoregressive models, thereby permitting the reconstruction of any signal having a missing portion, irrespective of whether or not the length of the missing portion is greater than the short-term stationarity duration of the signal.
