Distributed joint source-channel coding of video using raptor codes
(United States. Patent and Trademark Office, 2012-11-20)
A video encoder system includes a base layer and an enhancement layer for encoding video data. The base layer encodes a reduced quality version of the video data to obtain base layer data. The enhancement layer encodes the ...
Compress-forward coding with N-PSK modulation for the half-duplex Gaussian relay channel
(United States. Patent and Trademark Office, 2011-03-22)
Systems and methods that implement compress-forward (CF) coding with N-PSK modulation for the relay channel are disclosed, where N is greater than or equal to two. In the CF scheme, Wyner-Ziv coding is applied at the relay ...
Source-channel approach to channel coding with side information
(United States. Patent and Trademark Office, 2011-09-13)
Code designs for channel coding with side information (CCSI) based on combined source-channel coding are disclosed. These code designs combine trellis-coded quantization (TCQ) with irregular repeat accumulate (IRA) codes. ...
