Abstract
Uncompressed video transmission has recently attracted research attentions since it ensures ultra-low latency, high video quality, and low complexity. In this paper, we propose a real-time uncompressed video transmission system, where unequal power allocation (UPA) strategies are adopted to maximize the peak signal-to-noise ratio (PSNR) while considering the peak-to-average power ratio (PAPR) reduction. Specifically, the relationship between the bit error rate (BER) and the mean square error (MSE) of this system is established. Based on the relationship, a group of optimization problems are formulated and UPA schemes are proposed through solving these problems. Among all strategies, UPA with an adaptive Hadamard switch is finally adopted in the proposed system, because it outperforms other schemes in PSNR performance under both the total power constraint and the PAPR constraint. Simulation results show that the PSNR of the reconstructed video is improved largely compared with reference methods.
