A Content-Based Precoding Solution Designed for JPWL Transmission
This paper presents a content-based pre-coding solution for the transmission of a Wireless JPEG 2000 (JPWL ISO/IEC 15444-11) image. To ensure the Quality of Service (QoS), the authors exploit the channel diversity with a Closed-Loop MIMO scheme. It relies on the Channel State Information (CSI) knowledge at the transmitter side that diagonalizes a MIMO channel into several hierarchical SISO sub-channels. In the proposed scheme, the JPWL code-stream is divided into hierarchical quality layers passing through the SISO sub-channels. According to this strategy, they propose a new content based pre-coding algorithm to maximize the visual quality in reception.
