The nonlinear mapping relation between the complex Weibull covariance sequence and Gaussian covariance sequence is derived. Based on this mapping, a simulation scheme for specified Weibull envelope distribution and complex covariance sequence is developed. The proposed method has been tested with many different examples, and the results indicate that the scheme works very well. The constraints on the covariance sequence of a narrowband process and the compatibility problem are discussed.<<ETX>>","PeriodicalId":345412,"journal":{"name":"[1988] Proceedings.

This method, which is algebraic in nature, is easily applied to practical coding problems, such as that of finding spread-spectrum frequency-hopping patterns with reduced cross-correlation noise.

Both algorithms have been implemented in software, and their performance has been evaluated. The first pitch-extraction algorithm (PEA Hash 1) uses center clipping and infinite peak dipping for time-domain preprocessing before computing autocorrelation while the second algorithm (PEA Hash 2) nonlinearly distorts the speech signal before center clipping and autocorrelation computation. PEA Hash 2 provides a better pitch detection estimate than PEA Hash 1 and also eliminates the need to adjust critically the clipping level threshold. The initial results obtained by comparing the average gross pitch error rate suggest that PEA Hash 2 is better (by a factor of two or more) than PEA Hash 1.<<ETX>>","PeriodicalId":345412,"journal":{"name":"[1988] Proceedings.

Because the initial variances of the measurements used in the estimation are uncertain in a practical situation, a tracking filter can be optimum only in steady-state. The steady-state error of a version of the Kalman filter, called the alpha , beta filter, is analyzed under the assumption that missing data may occur. The results are developed for a constant-scan-rate radar. The number of intervals between valid data is modeled as a geometric random variable with the probability of valid data as a parameter. It is shown that missing data can introduce large additional tracking error for slowly scanning radars.<<ETX>>","PeriodicalId":345412,"journal":{"name":"[1988] Proceedings.
