Multiplexed predictive coding of speech
(2001) IEEE International Conference on Acoustics, Speech, and Signal Processing, 2001 p.741-744- Abstract
- In this paper we present a novel method for predictive coding with application to transmission of speech over packet-switched networks. Our method uses multiplexing to distribute a part of the information about a segment of each speech signal in several data packets while keeping the data packet rate and payload for that part of the information unchanged. We investigate three multiplexing schemes: a packet hopping, a Hadamard multiplexing, and an extension of the Hadamard multiplexing that exploits a nonlinear preprocessing and estimation method. We show by means of formal AB-preference tests that multiplexed predictive coding can lead to coders that are more robust to packet losses than scalar quantization and packet loss concealment...
