Title
Joint Carrier Matching and Power Allocation for Wireless Video with General Distortion Measure.
Abstract
In this paper, we present a cross-layer design for a family of OFDM-based video communications by jointly considering application layer information and the wireless channel conditions. Compared with traditional cross-layer designs, our proposed method targets to efficiently transmit video data generated with some emerging techniques for better wireless transmissions, where the video data are divided into multiple chunks and each chunk contributes independent distortion to the entire video quality. To minimize the end-to-end distortion, we formulate a generalized optimization problem and derive a joint optimal carrier matching and power allocation scheme. Rather than depending on a specific video encoding method as done in the conventional work, we intend our design to be applicable to a general family of new video schemes. We apply our proposed method to two applications, the enhanced analog coding and the uncompressed video transmission over OFDM. In both applications, the performance can be improved by adopting our scheme. Simulation results validate the effectiveness of our approach in achieving significantly better PSNR and visual quality compared to reference schemes.
