Linear Subband Predictive Filters for Wideband Signals
Proceedings of the International Conference on Circuits, Systems, Electronics, Control and Signal Processing
In this paper we present the design of multiband linear subband prediction (LSP) filters for wideband signals. A wideband signal is divided into narrowband subband signals via an array of lowpass/bandpass filters. A linear prediction filter is designed for each subband channel, which has its own designated frequency interval. The filter coefficients are fixed throughout the coding process. A closed form bound on the error of prediction shows that the LSP approach is accurate for wideband signals, which is further supported by simulations.
