A fixed point computation of partial correlation coefficients
J. Le Roux, C. Gueguen · IEEE Transactions on Acoustics Speech and Signal Processing · 1977
This paper introduces a new computational algorithm for the partial correlation coefficients of a linear system given the covariance of its output when excited by a white input noise. Although derived from Levinson's well-known procedure, the proposed algorithm does not make use of the usual parameters in the linear prediction recursion. It may be implemented using fixed point arithmetics. Application to speech waves is emphasized.
