Hidden Phase Space Reconstruction: A Novel Chaotic Time Series Prediction Method for Speech Signals*

Jingjing Li;Qijin Zhang;Yumei Zhang;Xiaojun Wu;Xiaoming Wang;Yuping Su

Chinese Journal of Electronics
Year: 2018 | Volume: 27, Issue: 6 | Journal Article |
Speech signals are nonlinear chaotic time series. This paper proposes a novel speech signal nonlinear prediction model with the hidden phase space reconstruction method. The parameters, embedding dimension m. time delay \tau and model structure are solved simultaneously, breaking the restriction of phase space, which needs to be reconstructed before modeling for the existing prediction method....Show More

A Low Memory Design for Hybrid-ARQ Systems

Qijin Zhang;Zhenqu Zhao;Hongwen Yang;Hongkui Yang

2008 4th International Conference on Wireless Communications, Networking and Mobile Computing
Year: 2008 | Conference Paper |
Cited by: Papers (2)
In this paper, we propose a low memory design for Hybrid-ARQ systems that combines the new transmission with previous transmission either with Chase combining (CC) or code combining (IR: incremental redundancy). When the current transmission is decoded in error, the channel inputs to be stored for combining with next transmission are quantized with fewer bits by simply dropping the last few least ...Show More
