Predictive quantization is a simple and effective method for encoding slowly-varying signals that is widely used in speech and audio coding. ...
It has been known qualitatively that leaving correlation in the encoded samples can lead to improved estimation at the decoder when encoded samples are subject to erasure. ...
Thus, a jump linear system is a standard linear state-space system, where each system matrix can, at any time, take on one of possible values. ...
