摘要： A method for reducing a computational complexity of an m-stage adaptive filter is provided by determining a weighted sum of backward prediction error squares for stage m at time n, determining a conversion factor for stage m at time n, inverting the weighted sum of backward prediction error squares, and approximating a weighted sum of forward prediction error squares by combining the inverted weighted sum of backward prediction error squares with the conversion factor.

摘要： A method for reducing a computational complexity of an m-stage adaptive filter is provided by expanding a weighted sum of forward prediction error squares into a corresponding binomial expansion series, expanding a weighted sum of backward prediction error squares into a corresponding binomial expansion series, and determining coefficient updates of the adaptive filter with the weighted sums of forward and backward prediction error squares approximated by a select number of terms of their corresponding binomial expansion series.

摘要： A container for scaling fish prevents the scattering of loosened scales from the fish during scaling. The present container has an open top with liquid impervious walls and floor. The floor slopes to a drain, which may pass through the floor or through a low point along one wall. The drain includes a guard or screen therein, to prevent passage of fish scales or similarly sized articles therethrough. The container is filled with water with the drain capped, or the container is placed in a sink or basin which is filled with water. A fish may then be placed in the container and scaled, with the viscosity and density of the water precluding scattering of the removed scales. When scaling has been completed, the water is drained from the container, with the scales carried to the drain by the water flow and captured by the guard for ease of removal.

摘要： A container (10) for scaling fish prevents the scattering of loosened scales from the fish (F) during scaling. The present container (10) has an open top (24) with liquid impervious walls (14, 16, 18, 20) and floor (28). The floor (28) slopes to a drain (38), which may pass through the floor (28) or throug h a low point along one wall. The drain (38) includes a guard (40) or screen therein, to prevent passage of fish scales or similarly sized articles. The container (10) is filled with water (W) with the drain (38) capped, or the container (10) is placed in a sink or basin which is filled with water. A fi sh (f) may then be placed in the container (10) and scaled, with the viscosity and density of the water (W) precluding scattering of the removed scales. Wh en scaling has been completed, the water (W) is drained from the container (10) , with the scales carried to the drain (28) by the water flow and captured by the guard (38).

摘要： A voice decoder detects channel errors and loss of cryptographic synchronization using the change in spectral energy between sequential frames. The change in energy between frames is determined between corresponding LSP's of said successive frames and summed together. A running average of the change in energy for a predetermined number of frames is maintained. Current voice frames are eliminated based on the difference between the change in energy associated with the current frame and the running average. Accordingly, offensive audio associated with such channel errors or cryptographic synchronization loss is eliminated.
