Abstract
When independent records of sampled data from a common source are available, one method for combining these data while using Burg MEM spectral analysis is, at each iteration of the Burg algorithm, to compute separately sets of numerator and denominator terms for the reflection coefficient, and then to compute the reflection coefficient as the quotient of the averaged numerator and denominator terms. The effect of this form of averaging for the case of multiple records comprising two noisefree complex sinusoids is investigated analytically. It is shown that when the relative phase between the sinusoidal components varies randomly from record to record, bias terms in the first and second reflection coefficients are inversely proportional to the number of records processed.
