Abstract

In this paper, we propose a novel energy-minimized optimization algorithm for image coding and transmission over wireless channel. In order to reduce computational complexity of reaching optimal solutions, the presented algorithm makes full use of the intrinsic relations among the system parameters, optimization objective, and system constraints. We present simulation results to demonstrate that the proposed optimization algorithm is effective and it has much lower computational complexity than the conventional sequential quadratic programming (SQP) method. And the proposed algorithm is suitable for mobile image transmission applications.
